Blair created this backdrop decoration with a modern wedding in mind, but I can picture it used in other ways too. Like a backdrop on a modern fireplace mantel or mirror-less dresser, for instance. Supplies, which include a template*, are pretty basic and are available at any craft or office supply store. Blair hung her backdrop using fishing line, but Command Stabilizer Strips might be a good alternative for mounting directly to the wall. For the entire tutorial, visit Project Wedding.
*The link in the 'Supplies' list to the template isn't available. It IS available, however, in the first step in the directions.
