This is an addictive craft and kind to the environmet too as you can recycle all your own wine/beer bottles. I use the kind of bottle cutter that spins around the bottle whilst balancing on the rim but there are other options available. It's great fun making vases with your chopped bottles, here are a couple of mine. I used metal die cut shapes painted with glass paint for this one. The only down side is that they can only be sponge cleaned on the outside.
It would be great to see this art grow in popularity.
