I found a cute mug rug pattern at Quilt Addicts Anonymous, link here. The pattern is free, but you do have to put it in a cart to get the download.
I enjoyed making these tree blocks. I used Christmas fabric I already had and muslin for the background, but I did buy two yards of the green fabric I used for the borders, backing and binding. They finish at 8" before binding, so I added 1.5" borders to them to make them a little bigger for potholders. I put two layers of cotton batting in my potholders with a layer of insul-brite in the between the cotton batting. I like the scrappy trees, but I really like the tree where I used the Christmas light fabric on the entire tree. That is my favorite. I made seven of these potholders. Three for me, three for dear daughter, and I sent one up to my sweet big brother who is always looking out for me.
I have more fabric cut to make more of these blocks for a wallhanging. So that's what I'm doing in January, making home decor items for Christmas 2021.
