It’s called “Pockets to Go” by Atkinson’s Designs. I have had this pattern in my pattern box for some time, and decided that it was time to pull it out and make it (I have several of those patterns wanting to be made).
It has two zipper pockets on the outside of the cube. And, the inside has various sized cubbies. The bottom and sides are stiffened with Peltex. It is going to be a useful- quilting tool. And, cute to boot. Have a good weekend and I hope you
