I have so many projects in progress that several times when I was ready to finish a quilt I realized I had used the backing material on another quilt. Now I have the tops hanging on hangers waiting to be quilted and each quilt has a 2-1/2 gallon bag attached to the hanger with binder clips. The bag will contain the backing fabric, all the remaining fabric from front, the pattern instructions and sometimes the binding all cut, pressed and rolled up waiting for me to finish (long wait in most cases).....not enough hours in the day when you work full time.
I have project (pizza) boxes stacked up with fabrics I've pulled and patterns waiting to be started. The boxes work well for the piecing part, the hangers work well for the waiting to be quilted part. I tape a plastic page sleeve on the outside of the box with a picture of the quilt that I plan to work on.
