Thanks for your replies, I saw that at both places, and I wondered if it set solid or flexible? Because I couldn't work that out from reading the back. When using it for small things, its easier to be a flexible mold otherwise i'll ruin it just by trying to fish it out iykwim!
I'd be interested for sure if it sets flexible! I got some liquid stuff from trademe which has been working OK but its messy and really hard to get the finished product looking good.
