In the film the triangle squares start a little big and get trimmed to size, which is the easy way to sharp points. The chart gives the exact cut if you’d rather skip the trim.

Good to know

What size should I make a Two-Cloth Corner-Bordered Pinwheel block?

Any size that suits your quilt. 12″ is the easiest to sew, and 9″ or 6″ look lovely in a busy, scrappy quilt. It sits on a 36 by 36 grid, so a finished size that divides by 36 gives you friendly cutting numbers. The cut sizes for all three are on this page.

How many Two-Cloth Corner-Bordered Pinwheel blocks do I need for a quilt?

At 12″ you need 9 blocks for a wall quilt, 12 for a baby quilt, 30 for a throw, 48 for a twin quilt and 72 for a queen quilt. Sashing or a border between them means fewer blocks for the same size.

Is the Two-Cloth Corner-Bordered Pinwheel good for a beginner?

Yes, if you take it slowly. The one new skill is the half-square triangles, and the film at the top shows every cut, seam and press.

What's the trick to a neat Two-Cloth Corner-Bordered Pinwheel?

Sew a test Two-Cloth Corner-Bordered Pinwheel first and measure it. If it comes out the right size, the rest will too.
