the "mold" was one of those throw-away plastic containers that you get when you buy your frozen food at your local market. so yeah...the good news is you don't have to buy one, the bad news is you can't buy one.
just keep your eyes open, next time when you buy some prepackaged foods, see them as a potential molds...most of my "molds" were obtained that way
Lol, see...don't give me too much credit (wink), all of my food are super easy to make. Now the mold, yes they will do just fine, if not, you can always melt them, and re-pour the jello liquid back in mold.
