How do you tell if fabric is downproof?
I'm getting ready to make the dinos single-size down quilts. I have quite a bit of WalMart $1 fabric on hand, but am not sure how to go about testing it for being downproof. My dear departed MIL told me many years ago that the male dino was allergic to down so I've never made anything with down. I found out recently that one of his brothers is allergic to down, but he is not so down quilts, here we come.
