I am just dinking around with candles too and don't want to spend a lot. strain wax into milk cartins thru 4-6 layers cheese cloth. You may find small milk cartins like you got in school make a great size/ shape. School kitchen person of kid will save them for you. soup cans also good mold. Drill a hole in bottom for wick or not (using pencil to hold wick out of wax and into container.A penny makes a good weight or that guys suggestion of a fishing line weight.) Tappered molds. See flexible cooking pans at your grocery store, muffin pans make a nice size candle and a good storm light. smaller candles, ice trays. look at the 2nd hand store for other containers, use pam spray oil (generic ok) for release agent for metal. There is a candle clay to plug holes (in cans). A giant tack like device can be set in the bottom or your mold pour wax, cool remove tack and thread with wicking needle. I have't purchased or done this part yet, myself. The big secret is wick size. Books figure your using parafin or other things and the sugeestion for wick is too small. I am going on memory now , but i believe it is increase by 4. Wick scales .......-2,-1,0,1,2,3,4,....so if it calls for -2 you really need 2.. The other great secret is cut and soak your wicks in wax first, lay them out straightish on wax paper; straighten them more when cool. If wax cracks off it's ok, it's saturating the inside that counts. I found anything labelled candle mold making expensive,especially if you just want to dabble. Have fun!
