A friend of mine has been saving glass milk bottles for me. I haven't decided what to do with them yet, but have considered using a few for fun drinking cups. Then I came upon Jordan's fun DIY project to personalize glass jars and am now committed.
To create a professional-looking set of personalized glass jars, use paint pens (meant specifically for glass) and create a stencil using the font of your choice. For detailed instructions and photos, go over Oh Happy Day where Jordan's got a link to her write up on Project Wedding. Make a personalized set for your whole family and make a few extra for friends as well.
