As long as we're on the topic of multiple fabrics, please remember that I have to make all F8s fit into each person's mailing envelope. It's never a problem with a single swap, but if someone is working both groups, it WILL be a problem if more than a couple of you are sending two fabrics or more. Also, when returning blocks, if you are in two groups, getting a couple or up to three dozen blocks back AND asking for a return of fabric, I will have to use a larger package to ship back to you so be prepared for 1) increased mailing costs and 2) mail delays. It's easy for me to ship flat rate envelopes, not so easy for larger ones that aren't flat rate. But we can work it out, no worries...just be prepared. I'll look at the shipping costs for larger packages, including flat rate boxes, which should accommodate all that fabric. Will let you know what I find.
Edited to add: the medium flat rate box is $13.45. This might be the way to go for those of you who will be sending and receiving multiple groups and returned fabrics. The small flat rate box is $6.80, the same cost as the padded envelopes, but I don't know how much fabric it will accommodate. Might have to do a little experimentation here.
