This is a fun and "easy to do" project! You do not have to adapt it to a candle jar; a tin box would work well, and you can size the design up and down as well as change the colors in the project! I had etched the candle jar before working on the project, and that is really beneficial because your inking and rouging sets into the glass, not just on top of it because you removed the glaze from the glass. Detailed instructions are in the packet.
