I make all kinds of "mug rugs". I am now working on making a crazy patch quilt. I cut my foundation pieces out of left over light weight flannel, muslin, or even, no longer used bed sheets at about 5 1/2 " square. I then stitch my crazy patch pieces in various sizes to the foundation and square them to 5" squares. You may want to make the squares larger. I will put sashing between the squares; no need to use batting inbetween, then backing and machine quilt. So easy, and all from scraps. GiG
