I had to make another purchase but I believe it's well within the guidelines.
I'm in a class on the 19th, we're doing Ziggarut from Pam Goecke Dinndorf's book Colorific. Its a great book if you are interested. Anyway, I am using all fabric from my stash, a bunch of Marcia Derse fabric I bought in Anchorage a few years ago. Turned out I was a smidgeon short on the pinks so I picked up a fat quarter of a different fabric that I think will blend in. Since its only for about 5% of the quilt I feel ok about it.
