To make a real down feather quilt, you need to strip the fluffy part of the feather from the spine. It takes lots of work. Then you need to get feather proof fabric which is very tightly woven so that the feathers won't come through the fabric. It takes quite a while to gather enough for a quilt, but once you do it's like sleeping under a cloud and so warm and toasty, there's nothing like it. To make you quilt you can either sew channels and put the down in each one or make sort of like double channels so that there are no cold spots on your quilt. I used to sit in our small half bathroom to fill the quilts. That helps to eliminate feathers flying all over the house.
