Cutting chart, piecing steps and yardage for a Variable Star block that finishes at 9". The block is a 3 × 3 grid and each cell finishes at 3".
Cutting chart for one block
| Fabric | Cut | Size | Then |
|---|---|---|---|
| Main | 2 squares | 4 1/4" × 4 1/4" | 8 triangles (cut twice on the diagonal) |
| Main | 1 square | 3 1/2" × 3 1/2" | – |
| Background | 2 squares | 4 1/4" × 4 1/4" | 8 triangles (cut twice on the diagonal) |
| Background | 4 squares | 3 1/2" × 3 1/2" | – |
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 all the pieces out as in the diagram. The block is a 3 × 3 grid, and each cell finishes at 3". Sew neighbouring pieces into sections, then the sections into rows, pressing seams in opposite directions from row to row.
- Join the rows. The block should measure 9 1/2" now and 9" once it is sewn into the quilt.
