1 - 12 inch block from 44 inch fabric bolt width
This block is made using half square triangle units. To calculate size of squares to cut, divide desired finished block size by 4 and add 7/8 inch seam allowance. Each pair of fabric squares makes 2 units.
Unit A - fabrics 1 & 2; make 8. Unit B - fabrics 1 & 3; make 8.
Using 8 each of unit A & B, sew blocks together as shown in layout with 1/4 inch seam allowance. Press seams to one side.
[top]Tip: Put desired fabrics right sides together and then cut squares. This way, square pairs will already be matched.
