I don't have a picture but we used regular garbage cans that were about 30 gallons. A smaller can would probably have worked as well and would have been easier to handle. We cut a six-inch hole offset to near the edge of the lid, then put the lid on the can and drilled 1/4 inch holes through the lip of the lid and the top rim of the can. We bent pieces of wire into a "U" shape and inserted those through the small holes (from the inside - the six inch hole in the lid allowed access) around the perimeter then twisted the protruding ends. Drill only two small holes and secure with wire then drill the next two and secure those, etc. If you drill all the holes initially, you'll never get them to align properly.
