There is that framed pegboard from a vacation bible school I went to at age eight. I still have it downstairs on my shop wall with stuff hanging on it. The pegboard was cut to 16′ X 24″ then framed with pine cut to 1″ X 3/4″ and a 1/4″ dado was cut in one edge to insert the pegboard. I got to cut the 45 degree angles for the corners on an old wooden miter box then put the wood around the peg board and nail the corners.
I suggest #3 Galvanized Box nails here.

Of course the recipe holders I made in cub scouts were used by Mom for years,,, Wait a minute,,, More than 40 years later she is still using one of them.
Half inch plywood. One 3″ square. One 3″X3″ Right triangle.
Stand the triangle up in the middle of the square.
Nail and glue it there. Use a couple #4 Galvanized Box nails.
Take a snap type clothespin apart and drill a hole in one piece then ***** it to the ramp of the triangle. You want to ***** down the half that has the spring. Then put the clothespin back together. You should drill a pilot hole into the plywood for the ***** so the plywood doesn’t split.
A little paint before the clothespin goes on makes it “pretty.”

I hope this helps.
I won’t even mention the rubberband guns I let boys make while I was a scout leader,,,, You do NOT want a bunch of boys running around with them. 8>))
