Tonight from 5 to 8 pm at FLOR's Wooster Street store in Soho, you can design a mini-version of an 5x7 rug using sample squares. The winning design will go up against other design challenge finalists for the chance to be sold in FLOR stores (and the creator gets one free!). Robin Wilson will be there to help choose the winner and sign copies of her new book, Clean Design: Wellness for Your Lifestyle. Not in New York? The design challenge will be happening at stores across the country.
