Ever since I saw the super pretty frosted blue sake bottles they sell at the local SAQ, (that's liquor store in Quebec-speak) I've wanted to use them for something. I always feel bad about throwing out nice bottles, because it really is a shame when they could be reused.
Turns out I'm not the only one with this idea - now there's a shock :p
YAVAglass (both on Etsy and Artfire) makes really nice glasses from used bottles of root beer, cream soda, wine, beer, you name it.
I especially like the two sets pictured, and now I might just buy some from him instead of risking my own fingers - you don't want me near an open flame and potentially broken glass, take my word for it. (Although I will save those sake bottles, just in case)
