Need to make a mold? Use your kids’ (or your own) Lego blocks.

Using a large Lego base, build up the blocks as you would a brick wall, with each new layer overlapping the seams of the layer beneath. This will form a tight seal.

Create whatever form you need, be it large or small, and fill it with silicone or resin (it even holds reusable, reheatable molding material). I’ve never had the material seep through, and cleanup is easy.

The molding possibilities are endless!
