Are you one of those who mix up epoxy or other glues on scraps of whatever is to hand? Perhaps a bit of wood or plastic maybe? Well this is your saviour!...
Post-It sticky pads
Get yourself one of these pads, mix your glue, paint or whatever on the top sheet. Then peel off and dispose when finished with it. A pad lasts for ages. since I've been using this my workbench has been much clearer and less likely to stick an elbow or a valuable part to a cast off bit of scrap with glue on it.
