Tip #1--More or less just a discovery which I guess is what a tip is, huh. This large acrylic envelope is the exact width of a clothes hanger. It closes with a Velcro. Just close over the hanger and store in a closet or on a hook. Pretty neat stuff. I got this envelope in a class, but I imagine they are readily available in office supply stores.
You can see here how exactly the roll fits into the box. The box is from a 200 yard roll of foil.
