The use of these hangers as towel bars would be more interesting if you used vintage ones with advertising printed or impressed on them and then hung them on interesting hooks - old metal schoolroom hooks, antique doorknobs, tiebacks, etc.
Do you keep all your tape, twine and ribbon spools in a drawer? That can look messy, waste a lot of space and make it hard to find things. Try this great organizing idea. Screw a paper towel holder to the window trim in your craft room.
