At the hardware store, go to the section where they stock castors, bumpers, rubber folding chair leg feet ect. There will be a display of "Magic Sliders" or some such brand name. These have adhesive backs and are made of a slippery teflon material and are designed to go on the feet of sofas and other heavy furniture to make them easy to slide on a floor. They come in one size that's about 3/4 of an inch by 4 inches, perfect for the bass's edges. The ones I bought are about 5/16ths of an inch thick, enough to keep the top and back table edges from touching the floor. Give them a good hard bend so they match the curve of the bass and stick 'em on there. Some of you guys with real expensive basses might think twice but if it's that nice a bass, maybe you want to spring for the leather and ebony ones installed by your luthier. Peace-out
