Add 7/8" but most just add a full inch and then square them up :D:D:D
|
That's what I would do too. Start an inch larger and square them up to your finished size.

I'm using 5" squares with the sew around method to cut down to 5 1/2" pinwheels.Try cutting 6" sqs & see how that works.

The formula for the sew around the edges according to Ceil is:
size of block you start with minus .5, times 1.4, minus .5 for the unfinished size. So if you start with 6" blocks it would be: 6 - .5 = 5.5 5.5 x 1.4 = 7.7 7.7 - .5 = 7.2 trim to 7" Take off seam allowance and it finishes to 6.5". HTH |
