Alicia Paulson of Posie Gets Cozy has really bright, mod curtains in her living room that she made from fabric she found at reprodepot.com a few years ago. I'm hoping someone will recognize this delightful pattern and knows whether this design is still being made. I'd love to know more (and hopefully purchase a few yards as well). Thanks!
If you haven't already contacted ReproDepot — I'd start there. I'd also suggest IKEA, as they've recently upgraded the majority of their US locations with larger and better fabric departments that carry a wide range of really nice textiles (at a fraction of the price of similar designs from Marimekko). You should have no difficulty finding something similar to this design at IKEA.
