I always called them coasters, but nowadays they are sometimes called mug rugs. But maybe mug rugs are technically little quilts with a binding and everything, so maybe this is really just a plain old coaster.
Anyway, as part of my simple farmhouse Christmas, I am making coasters and napkins this week using some Debbie Mumm rustic looking fabric.
Just cut your squares the size you want. Mine are about 6 inches. You need a top fabric, scrap of quilt batting and a bottom fabric.
This is the first one that I whipped up and the corners are a little wonky, but I hope to do better on the rest of them. My old sewing machine doesn't want to do those corners, but with practice I can improve.
I hope to show you some more coasters/mug rugs and the napkins later this week.
