This link will take you to another page with LOTS of tutorials on all things molds! http://www.makeyourownmolds.com/how-to-make-molds
I have used their mold making supplies and find them easy to use, economical and handy to have on hand when I need 'just the right' little mold fast!
I had the chance to meet Chef Dominic last year and found him so willing to answer questions and offer suggestions!
