When I have small scraps, I cut them into 1 1/2 strips for a future rail fence quilt. (sometimes) i go ahead and sew 5 stips together and then make the squares for this quilt. I then put them in a small plastic bin with the directions for this quilt.
Depending on the size of the scrap, I also make 2 1/2 inch strips and put them in a separate small plastic bin. These are handy when I decide to make a table runner or other scrappy stuff.i.e. toppers, table runners.
All other fabric gets wrapped around pieces of cardboard or foam core that is cut 6 x 10 inches. This makes the colors easy to mix and match when picking for a quilt.
There is also a pattern where you sew the scraps onto a piece of muslim at an angle. These are really fun. I make the squares 13 inches. I now have 5 of these squares.These are lots of fun. Like everyone else, I have many projects started.
