Originally I think she was only suppose to have 6 participants but 12 of us showed up with boxes of fabric and I think by looking at them there was plenty more fabric in each one, enough for 12 blocks. I took more up and added to my own before it was handed out to somone. Everybody has to make 12 inch blocks. Can't wait to get my second box in two weeks so I can make another pattern from the collection with a totally different box to work with. At the end of 6 months quilt shop giving a lunch and gab session so everyone can see what 6 of their blocks look like so far.
