I found this post from Moda Bake Shop for quilted hot pads. I cut down this design for coaster-sized pads: I used 1" strips rather than 1 1/2", and cut the finished size to 4 1/2".
I see this as practice for quilting my Craftsy 2012 Quilt Block of the Month. I just started and have a couple blocks done now, but each block takes me a bit of time. I decided to go with echo quilting, which means I gotta figure out a different quilting design for each block.
It'll get done eventually!
