Ideas on decorating margarita glasses?????

FH and I are supplying the alcohol for the reception and we have decided to have margaritas and beer. My venue only supplies the glasses for the water, tea, and coffee. I was OK with the guest drinking beer out of "fancy" plastic cups but I wanted to have margarita glasses, not plastic. I want to decorate the glasses and offer them as favors. If people take them, great, if not that is ok also. I don't want to put our names or the date on them because I don't think anyone would want to take them home and reuse them. I thought maybe adding some "love" quotes with clear labels but I don't think those will last....I have tried searching online but I am far from the crafty kinda person...Any suggestions would be great!!!
