Please don't start cringing and/or laughing at me yet. I bought some books of sample upholstery fabrics and some of the fabrics are amazing...no 2 alike. All 100% cotton made in foreign countries and all different motifs. Count varies quite a bit so I did wash a few and sewed a row of them. Shrinking was a no brainer but fraying hadn't occured to me...colorfast was surprisingly good. Directions said dry clean only but that's not going to happen. My question is: can I proceed making a California king size quilt if I can get all the seams doubled so they cannot fray? They can trim down to 12' sq (after washing) which I would not even consider but huge size quilt and motifs say go for it. I think the recipient would like it and I hate to say it but some of the pieces are just gorgeous and I might not hate it myself.
