Tutorial here. The tutorial calls for Wonder-Under but I think next time I will use Heat n’ Bond instead. The place mats are about 11″ x 18″ … instead of folding the fat quarter in half, next time I’ll just sew 2 11×18 rectangles together. This will give it a cleaner edge. As you can see from the photo, the white is showing up on the bottom left of the place mat so I want to avoid that.
