Quick Triangles Baby Quilt - Free Pattern

If you are looking for a crib-size quilt top that you can piece together in one evening, this half-square triangles quilt pattern is perfect for you. It features 6 fat quarters of assorted fabric prints and large, 8″ x 8″ half-square triangles (HSTs), that you can make 8 at a time.

Finished Quilt Size: 38″ x 53″

Online Quilting Class

Fabric Requirements:

– 6 fat quarters (18″ x 22″) of coordinating fabric prints
– 5/8 yard white border fabric
– 2 2/3 yards backing fabric (allows for 4″ of overage on each side when quilting)
– 3/8 yard binding fabric
– Crib size (45″ x 60″) quilt batting… I like a high-quality crib batting like Warm & Natural (affiliate link)
To get started, break your fat quarters into three sets that match well together. Look at the colors as well as the scale or size of the design.

Spread out and stack two of your fat quarters, and trim to an 18″ x 18″ square.

Now, stack your 18″ x 18″ squares with right sides facing. Mark a diagonal line from corner to corner on one wrong side with a ruler and pen. Pin together the fabric squares at the corners to hold the fabric in place while you sew.

Take your fabric to the sewing machine. With the marked side facing up, stitch a line 1/4″ from the edge of one marked line, to both the left and right of that line. Repeat with the other marked line.
After you’ve stitched the four long lines, notice how the stitch lines go right through the center of the block. With your ruler and rotary cutter, cut the block into four equal quadrants using this center and the block’s straight edges as your guide. For more tricks on making HSTs at a time, visit my guest post at Sew Mama Sew.

Use your ruler and rotary cutter to cut along the line you marked earlier, through the center of your stitched lines. Repeat with the other blocks, and you’ll have 8 half square triangles.

Press the seams open with an iron. This is my Panasonic Cordless Iron (affiliate link) which I love!

Using a square ruler and your rotary cutter, trim each block to 8″ square. Line up the 45-degree line of your ruler with your half square triangle before you cut.

Here are the eight 8″ half square triangle blocks from just two fat quarters. Repeat with the other fat quarters, and you should have 24 total blocks.

Arrange your blocks in a 4×6 grid. I kept my blocks in a set order, with the colors pointing to the upper-left and the grays pointing to the lower-right.

With right sides facing, pin together the blocks in each row and stitch. Press the seams open.
Next, join together the rows with right sides facing, and pin at each seam. Stitch together the rows and press the seams open.

To make the border, cut your border fabric 5″ x the width of fabric, for 4 strips total. Starting in one corner, attach a border strip to the top, then trim the excess. Repeat with the bottom. Stitch the ends of these strips to the other to border strips you’ve cut for the sides, to lengthen them. Press the seams open, then stitch the left and right border strips to the quilt and trim.

Press the seams open. Baste, quilt and bind as desired. After quilting and before binding, I trimmed the borders to 4 1/4″ to keep them even all the way around. This pattern is very beginner-friendly, and I’d recommend it for showing off strong prints. I hope you’ve enjoyed my tutorial, which I originally posted at Sew Lux Fabric!

    Thanks so very much for this simple straightforward tute. I appreciate that you reblogged it from Sew Luxe; I have some perfect prints for it and I like that it can be sized to however many blocks is needed. Perfect-thanks , no really-thanks….

    I made this for my best friend’s first grandchild last year, and now that her other daughter is expecting, I will definitely be doing it again! I also used this technique to do a rag quilt. Thank you so much for this tutorial.

    Dear Lindsay, I love your quick triangles baby quilt and have a bunch of fat quarters that I would love to use.
    However as i started to measure them, some were only 17 inches wide. Is there a way that I can make the quilt using a smaller size square of fabric like a 16 inch square? I would truly appreciate your help. Thanks, Linda Steinhart

    • September 30, 2014 at 6:13 pm

      Hi Linda! Yes, you can start with any size of square. I chose 18″ to get the largest square possible, but you can certainly make yours 16″ or 17″. You’ll just want to follow the directions and measure your HSTs to find out what size to trim them. Yours will be a little smaller than mine, but not much. :) You can add a wider border if you’d like!

        This is my first time trying this quilt, I used character print so two of the squares came right all the other ones go side ways, is that OK or do they all have to face the same way, and if so how do I do that. Help

        • February 10, 2017 at 1:55 pm

          It’s okay if they face different ways! Some of mine, do too! If it really bothers you, you can always try to choose a non-directional print the next time. :)

        I am having trouble with the 8 in square. Can I cut t down on one side? I don’t have a small enough square ruler.

        • January 28, 2018 at 9:09 am

          Hi Donna, If you have a cutting mat with a diagonal line on it, can you place the half square triangle block on the mat, line up the diagonal lines, and use a regular long ruler to trim the edges?

  13. Anouk
    October 1, 2014 at 1:40 pm

    I did it and its wonderful, but the border I cut is not enough for the sides, its too short. What did I miss here? I cut 5/8 yards which is 22.5 inches. No clue what could have happened and now I am afraid to cut again I don’t want to keep cutting white fabric.

    • October 1, 2014 at 2:05 pm

      Hi Anouk! I cut 5″ strips from the sides, so that makes approximately 40″ long for each 5″ strip (from the 5/8 yard). I pieced together some of the pieces to make longer side strips, since those aren’t long enough on their own. If you look at the photo, you’ll see that the top and bottom are shorter, so you can cut a bit off of those to make the sides longer. Hope this helps!

    I tried this in early Spring, it was wonderful. I read and re-read you instructions, It was MY first patterned quilt, it turned out Amazing, I’ve done 3 more this year since, using different prints and bold, bright colors makes this thing POP! I actually love making the ‘easy’ squares. Thank you for the wonderful inspiration.

    Absolutely saving this tutorial! I made a baby blanket using pinks, greens, and teals with a grey fleece backing.

    My friend cried when she took it out of the bag, saying I shouldn’t have spent so much money on it. When I told her I made it, she started crying more and laid it across her belly and hugged it.

    Thank you SO much, Lindsay!

  19. February 11, 2016 at 9:11 pm

    Hi Lindsay,
    This is my first quilt and I have a stupid question. Are the squares trimmed to 8″ or 8 1/4″ to allow for the seams, so that the finished squares are 8″ after they are sewn together?

    • February 11, 2016 at 9:14 pm

      Hi Eileen! The squares are trimmed to 8″ so that they are 7 1/2″ when sewn (1/4″ seam allowance on each side). Good question!

    Hi Lindsay , I love this quilt pattern and so does my granddaughter. She is graduating High School in May. She asked if I could make this quilt for a twin size bed to have for her college dorm room for her graduation gift. I said what a wonderful idea. This is where you come in. I need your help to determine much material and how many squares I will need to make this for her. Excited to get started. I await your expertise advice and assistance in measurements and fabric amount. Sincerely, Grama Debbie

    • March 24, 2016 at 3:28 pm

      Hi Debbie, It looks like an average twin quilt is 65″x88″ (or 93″ length if it’s a twin XL which a lot of colleges use). Each block is 8″ square before being sewn, so if you use a 1/4″ seam allowance they’ll each be a final size of 7 1/2″ square. If you do 7 squares across you’ll have a width of 52.5″ after assembly. Cut a 6 1/2″ border on for side. You’ll loose a 1/4″ seam allowance when it’s attached to the squares but not on the binding side so in the final quilt you’ll end up with 65″ across. Do 9 squares for the length for a total length of 67.5″ after assembly then add a 10 1/2″ border on the top and bottom for a total length of 88″. That’s 63 squares total (7 by 9). You can make 8 squares from 2 fat quarters so you would need 16 fat quarters total to make 64 squares. You can add an extra row of 7 more squares to the length if you need a twin XL length and make the top and bottom borders 9 1/4″ for a final length of 93″ and you would need a total of 70 squares/18 fat quarters.

      You’ll want to double check all of that math before you begin. Those numbers haven’t been tested or verified with any kind of quilting program so there may be some errors. You’ll have to let us know how it turns out!

    This is a very fun quilt to make and I have really enjoyed this free pattern- thank you! This is the pattern that got me started quilting- something I said I’d never do! Never say never! I’m addicted to quilting now!
    In the original pattern posted on Sew Lux Fabric, the amount of material indicated for the backing was 1 1/2 yards, which I believe is the correct measurement. In the above instructions, it states 2 2/3 yards for the backing, which is quite a bit of excess fabric (which will, of course, come in handy for some other project, but still…)
    I also found that the 5/8 yard for the white border fabric was cutting it pretty close, literally! I got 3/4 of a yard, which allowed me to add length to the white border strips at an aesthetically pleasing place, with that seam lined up with the seam where a row of the 8″ squares are joined together.
    I have made a few longer versions of this quilt using 8 fat quarters (making the quilt 4 squares wide and 8 squares long) and adding the appropriate amounts to the binding, border and backing fabric yardage (easy to do with just a bit of math!). It makes a nice size “nap blanket” for an adult and a great gift for a friend!

    • April 28, 2016 at 4:40 pm

      Thanks for your comments! You are right… I only used 1 1/2 yards for the backing. Another reader said she had trouble with this amount of fabric, so I increased the amount, but I always tend to “skimp” so I can conserve fabric, though other quilters like to have a lot more overhang. :)

    The only this that’s missing for this beginner is how to put it all together and the binding fabric steps. This is my first first quilt. So is it add the border, then batting then back fabric like a sandwich, then………??????

    Hi Have started this quilt, cut out the blocks & am now ready to trim to 8″ square. Only got a 6.5″ square ruler so how would I ensure that the blocks come out at 8″? Is it just a question of working out how much to trim off all the sides or is there a much easier way

    November 7, 2016 at 8:29 pm

    I don’t have fat quarter’s I need to purchase fabric for this baby quilt. How much would I need for a design like this? Thank you for your help. First quilt!

    Thank you for this pattern and tutorial. My mother in law asked me to make a quilt for my daugther when she gave me a bundle of assorted flannel. I found your Quick triangles baby quilt on Pinterest. It was exactly what I was looking for. This quilt was easy to do. Your tutorial is clear. Making this quilt is a breeze. I finally finished the quilt last night and I’m very happy, this quilt is beautiful. I posted pictures on my site http://www.marmailleettalonshauts.com/couture/diy/?p=972 and added a link to your tutorial.
    Thanks! :)

    Do you pre wash your fat quarters?

    • September 29, 2017 at 5:23 pm

      Hi Julia! Nope, I just iron them before cutting.

        How did you do this quilting was it a long arm machine? By hand? A darning foot? Other? And how did you come up the design it looks different on the border and the middle and in the corners.

        • October 8, 2017 at 1:55 am

          I used my home sewing machine with a free motion or darning foot! I was just playing around with designs I found in books and online.

            October 8, 2017 at 2:04 am

            Holy moly that’s inspirational, the whole quilt was done that way? With a regular straight stitch? I’m at the quilting step is why I ask….

    I am loving this pattern. i sew by hand and this one is easy to do without a sewing machine. I appreciate the pattern. I do have one question, and I might have missed it, Do you have a print friendly version available? I don’t spend much on a computer and I would love to be able to work on it on the go.

    this is a wonderful and simple crib quilt design. I shopped today and couldn’t find fat quarters in colors that I liked. should I consider making them myself? any tips?

    • January 14, 2019 at 9:42 pm

      Oh yes, you can buy a half yard of fabric, and just cut that in half to make two fat quarters! So you can make your own from yardage.

  35. Catherine
    May 15, 2019 at 11:06 pm

    Hi Lindsay,
    Have assembled all my fat quarters and now realize that one of my fabrics — Dear Stella Monkey Play date — has too large a print to look good as a triangle unless I do what is apparently called “fussy cutting.” As you can tell,I am a beginner! Can you please tell me how big a square or better yet triangles I need to cut? I bought that 8” square ruler you show in your pic. Just four 8 x 8 squares?

    • May 16, 2019 at 9:36 am

      Hi Catherine! If you are going to do these half square triangles differently, but cutting two squares, then cutting in half diagonally into triangles and sewing together, try to cut your first squares at 8.75″. Then cut in half once diagonally. Sew together the triangles into an HST with a 1/4″ seam allowance. Then trim the finished HST to 8″ square. Do a test block before you cut all your fabric. Good luck!
