if your crafty try making some! its fun, and you can personalize for the use or spell! try using melted wax mixed with crayon for color (big brands work best because they are mostly color which is why restaurant crayons are so waxy, they have little color mostly wax)
then pour carefully into a mold but not glass! you could break it, unless the glass isnt too cold. also remember to add a wick :D try plastic or cardboard! then either pop it out (carefully... this part can hurt because its so easy to pull out the wick) or cut it out to fit the shape of a glass container, or whatever container you choose. :D i have a trick to add herbs and sents if you want! just mail me!
