LET'S RESIN Silicone Putty,1LB/40A Silicone Mold Making Kit, Non-Toxic,Strong&Flexible, Easy 1:1 Mixing Ratio for Reusable Silicone Molds, Resin Molds, Soap

This stuff comes in blue or yellow. The blue, imho, creates a better, sharper impression. But they both work great! I use the molds I make with both resin and clay. Mostly clay. The blue molds stay sharp over many castings. I have been using this stuff for years. Highly recommend!

This was super easy peasy - even for a non-crafty non-artistic individual like myself. We have an antique armpit that was missing a bit of unique trim. I could not buy the trim in a store. I decided to use this to make a mold based on the existing trim a little bit of needing of the Play-Doh like substance. I pressed it into place and voilà. I had a mold. It worked like a charm. I then put wood filler like stuff into the mold and painted it and now unless you look closely and you can't even tell that I fixed it this way. This is a fantastic product and so incredibly easy to use.

Exactly as described. Easy to use. Highly recommend for beginners.

I followed the instructions, and my molds will not form without imperfections. i have tried 6 times. very disapointing.
