This may be one of those dumb questions... I want to make a simple box to fit into a shop drawer to hold some parts. I have some left over less-than-1/4" ply that I'd like to use. How would you suggest I join the edges? If there's enough surface area to do butt joints that will give me reasonable strength, I'd do it, just for simplicity sake, but I don't know if it would work. What are your suggestions?
