This heavy project is something I did for my son, DIL and two GS's. They have a king size bed. I used their old jeans, fussy cut them on grain, and sewed them with a flat "seam" (laid one raw edge over another) and used red thread with a double jeans needle. Yes, there was much fraying, but I snipped those after the sewing was done. I made use of the pockets and special "items" from the jeans. Pockets were trimmed and sewn closed before using them.The pillows have removable covers. The cover is not quilted. So much for that venture!
Thanks for looking!
