Hot on the heels of Levi’s, Scotch & Soda, and G-Star Raw, yet another national chain is opening up off of the Bedford stop. The Shade Store, a maker of shades, blinds, and drapery, will add a Williamsburg location to its 34 nationwide showrooms next month. Signage has gone up on the corner of North 4th and Wythe, just a block from the J.Crew and Ralph Lauren stores. The Shade Store already has showrooms in Soho, Midtown, and on the Upper East and West Sides, but now residents of the swank new luxury building at 50 North 5th— where a one-bedroom goes for $3,695 a month– can go right downstairs to buy some blinds. Which means it’s going to be way harder to watch football games through everyone’s windows.
