I agree with those who advised you to to buy it if you like it and buy 3 or 4 yds if you really like it. I have 2 1/2 yds of fabric I really like and wish now I had bought at least 4 yds.
Shops buy fabrics and sometimes the manufacturers will make more if it is really a hot seller sometimes they don't and the shops really don't know until they ask or try to reorder. The fabric reps really try to keep up to date on this but it's usually ??????????? I know this because I have a small quilt Shop.
