For the project I am currently working on, I am doing a bunch of candles inside bottles. From those I am going to make a chandelier type thing. It took a while before I found the right tool to drill through the glass (so that air gets into the bottle) but besides that the project is just pretty slow pace but coming along. I'm just putting a wick inside the bottles and then pouring in wax, so there's actually a homemade candle inside the bottle.
