I made this very easy, very simple cup mug rug for a customer whom bought a lot of my house mouse stamps. I'm hoping she's enjoying it!
My square is 6 1/2" and I used warm and natural batting inside. I sewed an X on the square (corner to corner) then I added the binding piece by piece while trimming each way. The next time, I'll sew my binding strips together and make sure that it is machinable binding. This way I will be able to finish up the mug rug quickly.
Enjoy!
