Beautiful fabrics! I'm probably one of the ones who you refer to that their stash is ahem "rather large". Lol.
I have done some swaps here on QB with a lady from Australia. When she told me the prices on fabrics over there I about fainted! A couple of times I bought fabrics for her and she reimbursed me. She said even with shipping it was still several dollars cheaper per yard (or meter) than if she bought them there.
