I'm a bit confused about the "sets of 8" issue.
I think I'm clear that each bag of 10 must have 10 different fabrics, and that the bags I send can be made of the same set of 10 fabrics, or they can have different fabrics as long as any one bag does not have any duplicates in it.
So where does the "8" come in? Does that mean if I want to do two sets of 8, I'd need about 20 fabrics? Or can I send 16 identical bags?
Here is a picture of what I've pulled from my stash.
