I got out some 1/2" hexies and some Central Park and Sunkissed fabrics and started stitching.
It was kind of difficult to shape it to the curve of the glass but I think it turned out great! I love having these cups at work, helps me drink more water. We have a good ice machine (I work at the hospital) so I enjoy cold drinks all shift long. Now, no one will pick mine up by mistake either, they will just look at it and shake their heads and laugh. I love it though.
