For co-workers who drink coffee (don't they all?)make some easy coffee sleeves. Get a cardboard one from your local take out to use as a pattern. I googled the directions but it is really easy and quick. Scraps of fabric. Scrap of batting. I made mine reversible and they really are great and fast!
For those who don't drink coffee - easy strip quilted mug rugs are good. Again scraps, solid back. I used a layer of flannel inside and pillowcased them for a quick finish.
Wanna see mine?
