cassiem, I use the Castin' Craft resin and just made some up this weekend. They took an extra day to cure because it is cold in my room since there is only one vent in the hallway upstairs, but they did cure.
Here they are! To add color, I used embossing powder found in the scrapbooking isle. Green in one and the others have purple. There are also tiny seed beads in the pendents. Resin bangle and pendents

The green square was the first attempt I did. I used a silicone brownie pan with it and the pieces came out cloudy and the part that was to the air remained sticky. I read this could happen with silicone moulds because they caused the resin to cool too quickly and so not cure properly. I have since coated the sticky side with Sculpey glaze which worked, and some I used something called Gloss Accents and that also cured smooth and shiny.
The pendants and bangle were done using actual resin moulds in a flexible plastic. They finished curing yesterday and popped right out. They are completely clear and the part that was to the air is also very clear and smooth not sticky at all. They are still a tad flexible so once they harden up more (assuming they will) I will trim off the excess resin that went above the top so the edges are even.
The Castin' Craft is pretty easy to use since you use equal parts of it. I wish they had the bigger bottles at Michaels since I have only used the stuff twice now and my bottles are already half gone!
