The Treehouse Club by Sweetwater for Moda Fabrics. From Sweetwater: This collection started with a trip to the mall. While standing in the kids' department of a favorite clothing store, we spotted a little t-shirt that read "The Treehouse." That was it! We added the word "club" because everything is better in a club, right? Sometimes we get lucky and find just the right theme, and that makes the designing process so much fun. The Treehouse Club is definitely one of our favorite collections because everything works so well together. From the tiny houses in the "clubhouse" to the colorful circles in the "tire-swing" design, every print relates to an actual tree house.
