Simple, shabby summer porch decor: pennants cut from 4"x1/4" balsa wood, sawn at 20 degrees & stapled to twill tape. (Or use jute, ribbon, whatever you like. I always default to twill tape because of its herringbone weave.) Balsa is so soft that I used a desktop stapler to avoid splintering. Secure to cup hooks on the back of a salvaged window frame, et voila! UPDATE: I've recently seen unfinished pennant shapes at Michael's. A little pricier, but certainly quicker!
