What should you cut?
Nine squares at 4.5 × 4.5 in: five dark, four light.
| Finished / unfinished | 12 in finished; 12.5 in unfinished |
|---|---|
| Seam allowance | 1/4 in included in cut sizes |
How do you assemble it?
Sew three rows of three with 1/4 in seams. Press alternate row seams in opposite directions, match intersections and join. Math: 3 × 4.5 − 4 × 0.25 = 12.5 in unfinished.
