I save empty tp tubes- lots of uses.* For binding, I slit one end, put an end of the binding in it. Then I roll the binding around the tube and put it in a bag that has a handle. I hang it on a knob on my sewing table and sew away. Binding unrolls ad is out of the way and NOT on the floor gathering dust & thread.
*Other uses: slit all the way - slip over gift wrap paper to keep it from unwinding; slip over embroidery stabilizer to keep it from unwinding AND write what kind of stabiizer it is on the tube. Don't slit and use to corral extension cords and all those charger cords that are messing up your drawers.
