I have been meaning to paint a few clear glass vases and jars after I saw this post over at Table Tonic and I finally got around to it this weekend. It is simple to do. Just swirl the paint around the inside of the glass until it is fully covered, tip out the extra paint and you are done.
I have noticed the paint hasn't stuck well to some of the jars. Maybe I missed a step but they don't look too bad arranged together in the kitchen display cabinet.
