Directions Completely cover the outside of the cylinder with stickers, stamps, and labels. Use white glue to attach, if necessary. Make a small slit in the plastic lid big enough for coins to fit through. Put the lid on and tape it down securely. Use colored markers to decorate or conceal the tape. There will be more incentive to save pennies when the bank has been self-constructed. When the can begins to fill, open a bank savings account so your child can deposit his coins.
