The Inspired Room is hosting a party dedicated to gallery walls. I've had fun putting mine together and like the clean lines. I bought my acrylic frames at AC Moore. They have 4 clips that hold the frame together. I purchased crisp white mattes from AC Moore as well. Sometimes the clips don't hang on the nail real well. To the rescue is 3M Command velcro. I use the small strips specifically made for picture hanging. Not a frame has fallen down since.
