How it goes together
- Step 1
Cut your pieces
Cut the pieces in the cut list. The sizes are for a 12 inch finished Indian Hatchet block and already include a quarter inch seam allowance.
- Step 2
Make the half-square triangle units
Sew each pair of triangles along its long edge and press toward the darker fabric. Trim every unit to size before you join it.
- Step 3
Assemble the block
Join the units into rows, then join the rows. Press as you go and square the finished block to size.
