Step 18: Make (or find) the worm bag lid
I found some 1/4" thick plywood around the studio. If you find some that is thicker, that will work well too and it will be less likely to warp if you want to sit on it, or put a plant on top. But the thin lid is nice because it will be lighter weight and easier to open.
Measure out a 20" x 15" rectangle and draw a line.
Get a jig saw with a wood blade installed in it, put on your safety goggles and ear protection and make the cuts. Be careful not to cut your table or saw horse. Or your fingers.
