I'm always trying for zero waste, particularly with my glass. I love glass and really prefer to never throw any of it away. I keep containers filled with all the left over bits from each type of glass I use.
One way I use some of it up is to experiment with colour combination by making glass drops. And sometimes I find a real winner and make a batch or 2 or 3, like the the colours below...
And they seemed perfectly suited for my Tabby Cat head image...making a cute but serious cat face fun and bright.
