This cushion cover is 32" square. I used 1/2 inch seam allowances. It's double sided mostly because I didn't have a piece of fabric big enough to cover the back without patchworking it.
Here's the fabric pieces I cut for each side:
- 8 x 7" squares in pale patterned fabric
- 32 x 3" squares in beige gingham
- 40 x 3" squares in dark brown cotton
- 128" x 5" wide strip of beige gingham for border
