Basically all my scrap quilts are "free" as I use the fabric that most throw away and I save from other quilts I've made. I also use the leftover pieces of batting. For the backs, I turn to pieces in my stash which once bought, I consider free! One of my first scrap quilts was done solely with scraps. however, I went to bed and while dreaming decided it NEEDED embellishments. So, I spent a lot of money on buttons and beads, including an antique set of buttons that were perfect. Well...my free quilt ended up costing about $70--!
