OK, I have decided to make a change to help some out who are wanting to use from their stash.
-
You make a set of 12 blocks out of the SAME pattern, but you can use ANY Batik fabrics to make your blocks 
- ANY 12" finished block (12.5" at time of mailing cause the 1/2" is your seam allowances) block pattern will work!
I hope this helps out those who are wanting to use what they have on hand. I am sending Patrice a PM now to change this on the first page.
