I have been looking for a “project” storage cart for. Long time.  It’s perfect.  I store quilt projects in each plastic sleeve and the best part is I can remove the container and take it with me to the quilt store to match fabric or to another room to work with. I do not use the wheels and it fits exactly under my sewing table!  This project cart is hard to find; I bought one years ago and wanted another.  Just found this and bought two!
