I have my 2 1/2" squares sorted in 3 different stages.
Fabric squares that I am trading:
I have a container that has 17 little cubby hole openings in it. When I cut my fabric I put one in each little cubby hole. This way no two fabrics are alike. When I need to mail a package I just take one out of the cubby hole and count it out and mail it away. Cubby hole #1 is always for me...that way I get one of each fabric I send to you ladies.
Fabric squares that I am keeping.
Most of them go into a really big boot box. (I am on #2) When I am working on a project.....
I have a really big tower, there are 16 containers tall (I buy them in 2's but you can attach them as you go.) I have each container marked with a color. As I am going through to pick out what I need I sort the others into these containers. They get sorted by color and some by theme.
Hope this makes sense. I have so far made 3 large size lap size quilts, and many other goodies with them.
