Fabric A: cut 2 - 7" x 7"
Fabric B: cut 2 - 7" x 7"
The key to a sassy pinwheel is choosing fabrics with high contrast or color differences. If you want a more subtle pinwheel, use fabrics with similar tones or colors.
Step 2: Draw a diagonal line of the back of two squares. Pair one square of fabric A with one of fabric B, right sides together.
Step 3: Sew 1/4" to one side of the line:
Turn and sew 1/4" to the other side.
Step 4: Cut along the center line using your rotary cutter or scissors.
Step 5: Iron seam open and trim to 6.5" x 6.5", making sure the diagonal line on the ruler is lined up with the diagonal seam.
Step 6 Lay out your block and sew your triangle squares together in pairs:
Iron seams open
Step 7 Pin your two rows together at the center seam for better accuracy and sew a 1/4" seam:
Press seam open and trim to 12.5" x 12.5"
