Here's a couple of scans and measurements. The block as I've done it here finishes at 10". So the quarter diagram is 5". Starting with a 6.5" piece of focus fabric, snub off the corners. You want to leave a 2" finished seam along the outer edges, make sure you leave your seam allowances!
The color band is a 2.5" cut strip of fabric. Starting on the snubbed corners, sew on strips around the snowball. I like to cut large and then trim down for accuracy, I'd be using about 4.5 x 2.5 for the first go around and probably closer to 8" the second time. Yes, you will be trimming off a lot if you do it my way.
The black is cut at 1.5" for a finish width of 1" which is a little hard to accurately draw. That leaves the corner triangle at roughly 1.5" finished, so about 2.5 normal cut or me, I'd be cutting 3" squares in half.
Only count the top corner of the block detail as accurate, I put in the color and black bands incorrectly on the bottom half but didn't catch it until after the scan...
