Craft Ideas for Teens?

Maybe origami would work. I bet you could find some free patterns if you google it.

How about mix in a jar recipes for a craft idea? You probably could find plastic containers to put the mixes in that would work just as well as glass Mason jars. You could do Russian tea mix or cookie mixes (just the dry ingredients along with the recipes).

Something that I have done with boys and girls, is business card size magnets. These come with a plain paper that you peel off to replace with a business card. You can purchase them at an office center. Outline one several times until you have as many as will fit easily, maybe 8, on an 8 1/2 x 11 piece of paper. Now, make copies of the sheet of paper. Save the original! Give the kids the papers and markers, colored pencils, stickers, whatever. Let them make art magnets, by designing abstract drawings or specific drawings, maybe just their name or the name of their favorite musicians, teams, etc.. Have them "stay within the lines," although the scissors will take care of that.

painting

Paper mache anything.

How about drawing with crayons or markers and maybe even trying to paint. Some of them may have hidden talent.

I work with at-risk youth & we do a lot of recycled/altered art stuff & our budget is zero - I get lots of stuff from 'trash' days. For instance, today I pulled some ceiling tiles from the trash that we can use to paint, cut-down (I would pre-cut) & make smaller tiles, use the one side as a cork board, decoupage etc..

How about origami? You only need paper and it can be as simple or as complicated as you like. Your local library would probably have a book on origami.
