cans (soup, coffee, etc) also make really pretty lumiaries (sp?). You peel the labels and clean them inside and out. Use a hammer and a sharp nail to puncture tiny holes all around the can in a pattern and then put a tea light candle inside and light it.
my 7 yr old son and i ues soup cans to make pen holders which he gives as gifts for holidays. Just cover them with paper (construction, stationary,scrapbook paper...how bout the comic strips from those newspapers youve collected?) to make the the pen holders look even better, you could lined the inside with paper also...or felt.
you can make palm trees from newspapers...my son did this at school. They rolled the newspaper and held it with a few strong rubber bands...take scissors and cut into the roll...not across..you are NOT slicing the roll. The other direction so you have long fringe on one end. stand it up and you have a palm tree. (to make it colored paint with poster or temper paints BEFORE cutting). You could also cut the fringes longer and they could be Pom-poms for cheerleaders...lol
i have seen airplane home decor made entiredly from soda cans. They are so cute. You could probably find instructions online for them.
also i have seen in magazines ...using soda cans and cutting and sometimes painting them to make decor for in your garden...sometimes they make them look like flowers, frogs, etc.
