Wine glasses..book quotes

I've been doing some thinking lately, and with my hours getting cut at work and bills that are always gonna need to be paid I thought about going on etsy and selling wine glasses like the ones above. (these are a few my friend and I did awhile back) I wanted to try and combine this with my love of reading. I thought about putting book quotes on them and decorating them. I'm not really an artist so they won't be to fancy. 

I was wondering if anyone knew anything about etsy. I've been looking at the site to see how things work, but I don't know. I guess I was wondering what (and if) someone were to buy these glasses what kind of price would they be willing to pay. I want to try and get some kind of profit out of it.

Let me know what you think? Would you be willing to buy these, and if so at what price?
