you can get parafin wax at the grocery store - just drop some crayons into it to get the colors right. Oh - you can also melt down the little bits of old candles that are too small to burn anymore. We used to melt ours in an old tennis ball container (a metal one) placed in a hot water bath. You need to be a little careful because the parafin is, obviously, flammable! We made these when I was a kid and it was fun. You can decorate pretty jars (mason jars work well and if you decorate the outside with torn up tissue paper painted on with watered down glue that's pretty) and then just pour the wax in. You can buy wick string at any craft store like Michaels. Make sure you tie the wick to a pencil or something and lay the pencil across the top of the jar so that it stays in the right place while the wax hardens.
