Bottles: The Medinet bottle was a bottle that I'd had for YEARS, just itching to DIY something out of it. The Bailey's bottle was a random bottle lying around. I mainly chose it because of its sleekness and its size.

Template of the bones of the hand: I googled "anatomical skeleton hand" and sized it a little smaller than my real-life hand. It definitely does not look undersized on the finished product. My template was white, which meant I had to paint it black later. This could be avoided by making the template from black colored paper from the beginning and using a subtle pencil to draw on it, like pencil lead.

Sculpting tools: I had a bunch in my crafting area, originally from Michael's. I only really ended up using 3 of the tools, as well as every nook and cranny of my hands.

Clay: I used DAS Scuplting Clay since that was what I had on hand. This is an air dry clay, which was a property I liked during the making of this. In a lot of the "fake" posts they recommend polymer clay. I didn't choose polymer clay for a reason, even though I work with it a lot in other situations. I didn't want the clay to slide around, and baking it without it moving would just be bothersome. It's also easy to dent when working on the other side of the bottle. I also liked the fact that I could layer air dry clay very smoothly - plus the fact that it was matte in the end, not shiny.

Glue: Apart from superglue to glue your finger bones to your template, find some good glue that works well on glass. There is a thread all about the best glue for working with glass right here on Instructables.
