I've noticed that banners and pennants seem to be gaining in popularity as a party decoration, and I can see why. They definitely liven up a room, don't they? Several of the pennants below are DIY, but since sewing is my craft weakness, I'm happy to report that there are also talented designers on Etsy willing to do the work for you. Here are a few ideas that could be customized to any theme or color palette... see below for links to resources &/or instructions.
