I only just came across this thread. I might be interested, but have a few questions, though. I have to admit, I didn't read through all twenty pages, so please forgive me, if I ask something which has already been asked.
1. Return postage: I wouldn't know if it's possible for me to buy American postage stamps here in Switzerland. I'll have to enquire about that and would need your estimate on how much postage is needed.
2. Fat quarters: Could I cut these myself from fabric? That would mean, that they might have no selvage. But I'd make sure to cut them the right size.
3. International fabric: Problem with quilt shop fabric is, that we get all the same brands you do, so don't get excited in your expectations.
I'll look into this and might join you. There's still plenty of time, as I see it.
