I bought 4 12 x 12 "Art Bins" from Joanns (also saw them at Michaels). All of the material for a project will fit in one. I promised myself that I would never have more projects going than I have containers (not counting finished tops). That way I have a choice of what to work on, but I am not overwhelmed with too many projects. Every now and then I make myself quilt 2 tops before I am allowed to start a new project.
