Quick Triangles Baby Quilt

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″

Fabric Requirements:

- 6 fat quarters (18″ x 22″) of coordinating fabric prints
- 5/8 yard white border fabric
- 1 1/2 yards backing fabric
- 3/8 yard binding fabric
- Crib size (45″ x 60″) quilt batting
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.

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!

    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!
