Anna over at Thimbleanna made a mug cozy a little while back. I have been wanting to try my hand at one. She didn't have a specific tutorial but did give enough info for me to make my own.
I measured around the mug, stopping at the handle. The base fabric, lining fabric and the thermal lite all were cut at 11" x 3". I cut the border fabric at 1" wide strips.
Place lining fabric wrong side up. On top of the lining fabric, lay the thermal lite or other batting on top of lining. Last, place the outer fabric facing up, pin in place and machine quilt. I used the checker board pattern as my guide. You can also do this by hand. Next sew on the binding like you would any quilt. Sew two buttons on each side of the quilt. Attach small hair elastics to put around each button to hold in place. you will be able to see that in the mug picture. Now you have a mug cozy to keep your coffee, tea or hot chocolate warm.
