Buckle up for tighter miters
Rubber bands work fine for clamping tiny boxes and frames. Typical band clamps help you deftly handle medium and large projects. But for small boxes and frames sized between those two extremes, I find it best to use shop-made belt clamps.
Simply buy a length of canvas belt strap and a small adjustable-slide buckle at a fabric store. Sew one end of the strap to the buckle. Now pull together your glued box sides just as you would cinch up a pants belt. You can't beat the control or price of these clamps!
