When it comes to holiday decorating, pool noodles are basically a layperson's floral foam block - but in a large size well-suited for a banister or a mantel - and in a bendier material that makes them perfect for wrapping around archways and edges. Do you have an arch-shaped window or door? A circular mirror? An oval coffee table that could use a little more pizzazz for your holiday party? Wrap a pool noodle around the edge, then fill in with garland.
