I don’t know why I don’t see improved versions of this arrangement more often, for Single Prong Display Hooks seem made for rolls, reels and spools. I actually use one to hold a roll of paper towels at the ready in my basement. There is even space to hang the Windex spray bottle behind. An orderly, easily-shopped arrangement of spools on Single Prong Hooks could be worthwhile. Though not an unmitigated merchandising success here, at least these shapes and colors make an interesting still life. The most basic of basic of the hook Taxonomy … All Wire Hooks for Pegboard and Slatwall. Note that many variations in frontwire treatment are easily possible.
