I love all the suggestions of embroidered shapes on the table runner instead of buttons--I think that will work much better. I've been working on the reverse side, which I had originally planned to appliqué as well, but I started messing around with stitch options,
found one I liked,
then found a second one I liked,
and I think they make a nice contrast to each other.
I think Theo likes it as well...
It's interesting to stick only with primary colors as I've never really done it, but it definitely feels very cheerful and vibrant. Now to pry the cat off of it and get it sewn together!
