We had canisters made up by a local sign company. A laminated sign displaying a picture of the future playground was attached with a industrial size paper clip. The canister look like the cylinder tootsie roll containers at stores. They have a slot at the top. We placed the canisters at area businesses. We average anywhere from $150 to $250 a week in donations. Our community is very small, so I imagine this would work great in larger communities. The best part is the canisters and signs were donated by the sign company.
We are a very small community and we have raised around $2500 with the canisters.
