It all starts with the window. Literally. Your window is the first opportunity you have to make an impression on passersby. I'm always amazed at retailers who don't give one thought to their window display or don't even have a window display. If done well, it should make people stop, look, (hopefully) smile, and then head for the door.
I try to change my window every month. As for the design, sometimes it's inspired by a color, new products, or the season/holiday. Often, it's a combination of two or more of the above. This year we seem to have an abundance of polka dots.....on scarves, bowls, mugs, and socks.....and I knew at some point they would find their way to the window.
