You know those shapes for kids to arrange to make various figures? Google Tangram if you don’t. This person played around with the tangram shapes & then duplicated the ones he liked in wood. Pretty cool. I guess it could be argued that this is not art, but what the heck, if you like it that’s all that matters. Besides you are being creative in how you use it. These could even be used to make quilt patterns, embroidery, collage (with or without decoupage glue), whatever your imagination comes up with.
This would make a cool piece of art for you wall IMHO. You could decorate all sorts of things like notebooks, bookbags, tote bags, whatever. Kids might like designing their own. They could make them in cardboard or plastic. Cardboard covered in fabric could look cool too. You can paint the pieces however you like. How about some in team colors for a kid’s room or a game room? Lots of fun. You could probably come up with designs yourself or buy an inexpensive tangrams set, often found at teachers’ supply stores. You could try using old paint chip samples but they would be on the small side–maybe would work on greeting cards.
