For candle making, you only need the candle making table. You can buy the ingredients there. I didn't recycle anything when I tried it. Just bought the wax and some colours. The Bits & Pieces are for fabrication, a different skill.
So far I'm a bit disappointed with candle making. I mean, with the candles not lasting long. They CAN be recycled again, though! Didn't really notice, but I think I got some wax from them. Also, wondering if there are any customization to the candles, like different holders and so on. The default holder is barely noticable.
