Estrella Mosaic Glass

Very pretty

The pieces come in a weird shape, so if you're doing a niche you'll need literally twice as much as you think (not the usual 10% overage). It's very thin tile and the edges are less finished-looking than I would expect considering the price. It's beautiful in my shower though and once there's grout you can't tell the edges looked unfinished before. Make sure you look at a full-sized sample before you purchase.
