DD1 is obsessed with collecting sea glass which is now filling a pot at home. I've said we can use it to make xmas decs but I could do with some ideas. I did see some lovely baubles for sale that someone had made by glueing the sea glass together so it formed a hollow sphere, but I can't work out how they did it, I presume they were made over some sort of mould, maybe in two halves and then joined? Not sure. Any other ideas welcome.
