Very basic list of supplies: bag of white chocolate chips, a few regular chocolate chips, lollipop sticks, and waxed paper.
First, melt the white chocolate. I use my microwave one minute at a time, stirring in between. You can also use your double boiler, but that is slower.
Spoon out a bit of white chocolate onto waxed paper, and shape it into a ghost with the back of the spoon.
Insert a lollipop stick into the ghost, and twirl it a bit to get it coated in chocolate all the way. (If you don't the stick won't really stay in and you'll lose your treat.)
Now just wait for them to dry. Ours were taking forever to set, so I popped them in the freezer, and they were ready in about 5 or ten minutes after that.
I found that my bag of chocolate chips made exactly 18 pops, if you are trying to figure out numbers.
