I made four mug rugs for my MIL for several reasons: she and my FIL were keeping us for the weekend, they are hosting one of my sons for the summer so he can have a summer job, and because I haven't made her anything for a few years.
The mug rugs are all a little different so that anyone can pick a rug and put their glass/mug on it and know which one is theirs. They are bright and happy and I got to practice my FMQ!
Pictured below are three of the four.
