We found these on our iced tea glass when out to lunch the other day. It was a hot day and the glass was sweating freely, beaded with cold condensation. A coaster was certainly in order, to protect the marble tables, but this little slipper surprised us.
It was made out of light felt and slipped over the base of the stemware. Our dining friend loved hers; she said that it kept the condensation on the glass from dripping on her when she took a sip. But what do you think?
Similar coaster slippers are available at Epic Gifts - $3.25 for a pack of 8.
