There is a table runner that I've made several times called ten minute table runner and it actually takes ten minutes.
The best part is you only need 1/3 yard and 1/2 yard. You sew the third yard to the half yard right sides to gether. Turn inside out and sew ends to form a triangle sew and place a button on each end to hold together. I've made a few longer for bigger tables. There is video on the Internet. Ten minute table runner. The one I like best is the one did with Valentine Fabric.
