| Fabric | Cut | Size | Then |
|---|---|---|---|
| Main | 1 square | 5 1/4" × 5 1/4" | 1 triangles (cut twice on the diagonal) |
| Background | 1 square | 5 1/4" × 5 1/4" | 1 triangles (cut twice on the diagonal) |

How to piece it
- Cut the pieces in the chart above. All measurements include a 1/4" seam allowance.
- Cut the squares marked "cut twice" on both diagonals. Each gives four triangles with the long edge on the straight grain: these are the large triangles in flying geese and hourglass units.
- Lay the pieces out as in the diagram and sew them together, matching the center.
- The block should measure 4 1/2" now and 4" once it is sewn into the quilt.
