Regarding the fraying: I had seen a description on John Flynn's website (
http://www.flynnquilt.com/workshop/FreeLessons/) where he will take a weed whacker to the quilt to fray it. I showed it to DH and he suggested a certain drill attachment that will do something similar without scaring me as much as weed whacking a quilt. So I think the fraying will be fine. Besides, I don't like how it looks when it's completely frayed! :D
