I make my own molds. They are easy and cheap.

Do you mix that resin up like it says on the container, in terms of ratio of the hardener??  Also, what kind of temperature can you make molds in?

I follow the instructions.  I normally make them in warm weather so I can work outdoors but have done a few in winter.
