LOVE the glass tiles! very nice color coordination
my personal experience is if you are planning on more tiling around your home, then definitely go ahead and buy the wet saw tile cutter. if only here and there then pass.
if not, depending on where you bought your tiles from, you may be able to get them cut for a small fee if any. i did this through Lowe's....didn't get charged for it because the tile cutter guy didn't price it out so i got lucky lol
