I went to walmart and in the kitchen dept I bought those plate holders or maybe there for pot lids but they have the rubber coating on them.Its wire coated white rubber.They come in different sizes.I keep all my rulers on these.I lay them on their sides so I can put several in each slot.I dont think im explaining it right but if you go their you can see what i mean.I even bought one for my accucut to hold dies.Their 1/3 the cost for the ones accut sells.
