there are lots of ways to make a scrappy quilt- some people cut their scraps into certain sizes & use a pattern- I've made lots of string quilts (strips of various widths/lengths sewn to a square foundation) and crazy quilt style blocks- where I cut a piece of muslin in a particular size (often about 10" is my favorite) then I use different sizes/shapes of scraps- adding them to the *foundation* until it is covered- the trim the edges even & sew the blocks together. some people like (planned scrappy) where they separate their colors - some people toss their scraps into a brown paper sack- sit down at their machine- reach in pull out a scrap- reach in pull out another one & sew them together- adding all around as they pull out each piece- until they reach a size they like- then just square them up... the great thing about scraps are- just be adventurous- try new things- have fun with them.
