It's dominos (obviously) with slips of pages from an old book stuck to them. I glued those little flat alphabet beads (painted them black first) to the backs of the dominos to run the elastic through rather than drill. The whole lot is sealed with nail varnish and spray gloss on the beads - I had them strung on a wire to spray so I didn't block the holes.
I've a few more ideas for these, but I'd like to know what y'all think. I wore it to work today and it stayed in one piece!
