Just an opinion, but do anything at all, really and it's art therapy. If you're hesitant because you 'can't draw', and try, then it can be frustrating because you end up not liking it yourself, you know? Lots of outlets other wise-every single person with the creative instinct has something. Please, please don't mind a couple suggestions? Just have done this myself anf for people-trial and error have seen things people seem to like in the end?
Those little squares of glass- buy anywhere like ebay, etc. Pair of glass/tile cutters, glue, wood-is all. Grout you can get at any Low's or home store, or craft store. Just copy a pattern of something simple like an apple, flower, whatever and fit the tile bits in however you like the way they look. Elmer's glue, fill in the background, grout the whole thing and it really, really is a nice, satisfying, GOOD piece, you know? I do flowerpots, too-turn them upside down and glue the tiles by layers or they slip down when the glue is wet. There's also beads- not as silly as it sounds, either. Most stores have packets of really pretty glass beads, and different wax strings. Simple macreme knots and beads in between-playing to make bracelets and things is awfully creative and satisfying also. An excersice in beginning-drawing for students? It's just a hand/eye thing, which teaches the brain, is all. You trace. Find pictures you like, and trace them on tracing paper, then fill them in by looking at the original picture. Your head eventually gets the general idea and begins to understand forms, is all. SORRY to 'teach'. Am a little sold on art as therapy, really, and as something everyone does actually have some kind of ability to do-one just has to tool around and see what that might be. OH! And clay, of course- it's tough to find good modeling clay in the stores. Playdough is as close to the 'real' clay as you can get. Anyway, you can get 25 pound blocks of 'real' clay from most brick/clay supply places, or maybe there's a potter close by you could buy some from. They tend to make it themselves sometimes.There's a wide-open world! Building slab-pots from rolling it out, or just scultures, or sketching in it with a tool, or take classes in throwing if you can. SUCH a cool outlet!
