Modular Strips

I have been working on a new modular jacket. I am apprehensive about joining the strips. The basic plan is based on De Colores from Ginger Luter's Module Magic. She uses a knitted bind-off to join, like you would if you were making reinforced shoulder joins. But I don't care for the ridge it creates at this point. Any suggestions?

This is Polworth from Rovings spun to bring out the color changes. I plyed it into a fake boucle, one ply thin and one ply thick. The strips are unblocked, but wonderfully soft.
