I was talking about clear glass gems earlier – as a counterpoint now, go for rich color – and you can still experiment with different shapes and tones 🙂
See? Really I’m just encouraging you to experiment. Try different shapes and colors. Don’t spend a lot of money. Do it yourself really IS a good idea 🙂
(and if you’re looking for something – but can’t find it – drop me a note, I might be able to help!)
