Hi, RenjiCat. I used to quilt last year before the depression hit me again. Shutting down all the things I used to love to do. I used crochet and knit, too. Can't seem to drag myself up to do anything I used to enjoy.

As far as your question, a lot of people use mulsin to back a quilt. I usually try to find a color that fits well with the colors of the quilt. I think it is personal preference.
