Recently I’ve started to use real Swarovski crystal strands around the borders of the invitation, with a few charms. I think it looks really elegant. I solder the entire strand so it is solidly attached. This one is made with amethyst crystals. The box sides are a very pale purple color. It has a mirror bottom but I also made a purple pad for the bottom, which helps to bring out the purple of the glass.
When I send out a glass box I put them in an inner box and then an outer box. My customers sometimes give me a card to put in as well. So I offer gift wrapping for the inner box if I ship directly to the recipient.
