45" wide 100% GOTS certified organic cotton poplin. We LOVE Charley Harper! If you've never worked with the organic poplin from Birch Fabrics before, you're in for a treat. This fabric is much more soft and buttery than a traditional quilting weight cotton. It's great in clothing, luscious in quilts and pillowcases, sturdy enough for totes. And the iconic designs of Charley Harper? They don't sit on our shelves for long.
