My current dilemma is do I pour the resin in the pendants before attaching the bike chain or do I attach the bike chain and then pour the resin. Both ways have pluses and minuses.
For instance if I pour the resin first it is easier to get a better seal and therefore I make less of a mess. The problem with this method is that you need to drill a hole in the resin. When drilling resin it is best to wear a mask because it creates a lot of dust and flying bits of resin (making a mess).
Using the second method you attach the bike chain and then pour the resin. In this method it is harder to get a seal (so you are cleaning up leaks and sometimes having to recast the whole project) but then you don't have to drill. Not that I'm against making a mess... far from it, some of the best crafting projects make my work room look as though a bomb hit it.
So here is one of my finished pieces.
