When you are using glue guns you will have the problem of hot glue dripping out from the tip. If you put a piece of cardboard under the gun that will solve that problem, but there’s another way. In the middle is a glue gun holder with a small ceramic tile under the glue gun tip. The neat thing is that the glue will easily peel right off the tile. And you don’t really need the holder, just a ceramic tile as shown on the right will work fine.
