I've got all the envelopes stuffed and ready to go. Will bring them to work tomorrow for mailing.
I used regular #10 (letter) size envelopes. I wrapped the fabric in plastic (cut pieces of plastic grocery bags), then inserted the package of fabric inside the letter I wrote to each of you with my preferences. I also adhered a label to each piece of fabric with my name, screen name, and Boomerang 8 Ruby group.
I didn't like the zip lock bags, they were too bulky with the zipper part and the only size bags I have are gallon size. Cutting the plastic grocery bags was a great way to recycle those and protect the fabric.
