|I have a dedicated sewing room, but storage space is still a problem. I recently started rolling up my fusible interfacings and storing them in 24" cardboard mailing tubes. I happened to have a dowel left over from some long forgotten school project and I use it to start the rolling process. The dowel makes rolling the lightweight interfacing much easier. I put labels on the outside of the tubes so I can identify the contents (lightweight, midwieght, etc.). I store the tubes in a large cylindrical basket along with my rolls of tracing paper.
Hope this tip helps !
