i used to own this really cool hair clip my dad brought me back from South Africa once - it was made out of three little biscuits (cookies!) which had been stuck together in a row, and varnished so they were super-tough, shiny and, most importantly, durable.
this week it's my boyfriend's birthday and I want to make him a keyring of his favourite biscuit, varnished! he would love it
does anyone know what I can put on the biscuit to make it really, really strong? i'm not convinced lots of layers of ordinary clear varnish will do the trick, and it's obviously going to take a good battering if it's attached to some keys. are there any specialist substances i can pick up from a craft store or something?
thanks in advance
