ok a selvage quilt: um if you hit your fabric stash or mine you would find it wouldnt take long at all for say the swirl one or the library one.. I toss them right and left as I dont do tiny things my eyes would flop out on the table if I tried to work them that hard. if you have a stash in theory you could raid it however this is important if you later needed more of one of those fabrics and then had no idea who made it.. trouble. or you could write notes Moda Marble Crimson or such on each of them as you cut them off and pin it to your fabrics. Otherwise it will take you as long as it takes saving them based on how much you quilt. OR you can post can you send me your salvages? see people will do this for you a few here a few there add up. good luck. best you not me!
