greetings. my name is carl and this is my first post on the white blaze forums. i was going to make some down booties to keep my feet warm on those nights that are approaching the limits of my quilt. however my sewing skills are weak and coming up with a pattern hasn't been easy. so i was thinking why do i need booties when i could just make a down bag that fits in the foot box of the quilt. sort of one large boot for both feet with a bit of elastic to secure it around my calves. it's not something i can walk around in but the booties were going to be only for sleeping anyway. the only things that might be a downfall is the weight and not being able to move my feet independently. anyone tried it? any reason why it wouldn't work? thanks.
