This craft is a lot of fun and VERY easy to do.  You need: -paint
                                                                                       - clean empty can
                                                                                       - shape sponges

Paint the can white and let it dry. Then sponge paint the can and let that dry.
You don't have to do this but if you put a coat of Podge-It gloss on the paint then it prevents it from chipping and makes it shiny.
If you use small cans then they can become a pen/pencil holder or even a small flower pot. If you use a big tin can then it can become a good sized flower pot or just a junk can.
