The tools I use in the video are a pin vise, which is not mandatory, but helps - I use the Mandrel Pin Vise (http://www.arrowsprings.com/html/holding_tools.html), and some leaf mashing pliers (http://www.arrowsprings.com/html/mashing_tools.html). Mine are the Realistic Small Curved pliers. You'll also need a bit of glass, and some leftover twisties.
And here's the video tutorial on how I made them. They're very easy and fast to make. Sorry for the bit that's out of the frame - I'm still working on the best way to record and will do better next time. Have fun with this!
