Here is a fast one! With a wool remnant and one seam, I have a fall runner. . . something that can take us from September to Thanksgiving. A pretty flannel would work, or another plaid you like. These colors just seemed perfect for our house.
It is super simple. Fold your remnant in 1/2 with the selvadges on each end. Seam it and press. Easy, peasy, lemon-squeezy.
