I have happily completed the placemats for my brother.
I bound them in four different colours of purple solids. And I backed them with some unbleached rough cotton. Here's the weird thing though. I almost think that these mats are reversible, because I really like the plain side too. The quilting keeps them from being totally boring and the binding frames them.
Maybe that is the side my brother should use when eating foods that have a propensity for staining. Just a thought.
