You will need:
1. A pretty glass, I used a Martini glass but you could use a chaphane flute, wine glass, anything you like!
2. Some gems/beads. I got my 'wedding confetti diamonds' from this seller here. A broken necklace would be perfect.
3. A tealight. A floating candle would be nicer though.
5. OPTIONAL: Some scented oil.
I don't even need to tell you how it's done do I? It's THAT simple, and I'm not even sure I can class it as a DIY!
NB: It lives on a table in the living room, not on my sink.
PS. I am having a sort out at the moment, and am putting some thing on my eBay. I have some up already, and will be adding more tomorrow. Check it out! It's going to the 'We need a bigger flat, pronto' fund.
