Fun idea! The initial investment behind making the molds make it a unfavorable thing for 1 off OCs. The molding process costs me about $100 to set up a mold, in addition to the time/materials to sculpt a master before we even get to the candle part! This might be able to work for fandom OCs or larger projects that want 20+ of the candles, but it's a hard thing to make a unique mold for a singular candle. Maybe a little different if an OC is a recolor - then we can talk!Jar candles would apply a lot easier to OCs, and I would probably like to look at doing that in the future. You can create some unique colors and layering effects which can make some fun OC candles, but without the molding process.
