I don't have a recipe for this other than to say go to a craft store like Michaels, and buy Wiltons Candy Kit for Pretzels. The instructions are fairly easy to follow, but the photo on the front of the box with the little girl and her mom is totally false advertising because this was definitely not a job for a little kid - at least not mine.
While the instructions are easy to follow, painting in the different colors into the mold was a pain in the ass. The end results however are pretty cool, although my crappy photos don't show that. And I can't say that I'd make dozens of them like I had hoped. I stopped at a handful and at most I'll pull the molds out again when I'm very bored or next Halloween.
