Sewing Directions:
Half Square Triangle Units:
Step 1:
Using a Medium/Blue 3″ square and a Dark/Navy 3″ square, make Half Square Triangle (HST) units as shown. Here are the steps corresponding to the images in the picture below going from top to bottom, left to right.
- Match up a Medium/Blue square and a Dark/Navy square right sides together. Mark a diagonal line from corner to corner on the back of the Medium/Blue square and sew 1/4″ (or a little less) on each side of the line.
- Cut along the diagonal line. You will have 2 half-square triangle patches.
- Open up the patch and press the seam allowance toward the Dark/Navy fabric.
- Square up/trim the units to 2.5″ square.
