So just to throw my two cents in on shell top making... I followed some previous advice and used gorilla glue.

Never using it for shells again. It was too temperamental, and a pain to clean up any excess. My £60 abalone shells are now on slightly wonky due to it. And I discovered two things... It doesn't cure well to plastic plants. And I'm fairly certain it's the cause for why all the resin on the front of the shells suddenly peeled off, luckily it's not done it to the back of the shells yet though.

Going back to my trusty e6000 next time!
