Enter for your chance to win a Haiku 2 Fabric Collection Fat Quarter Bundle. What’s neat about the Haiku 2 collection is that it comes in the same prints, but is made out of two different materials, so depending on what you’re looking for, you have options. The Lawn fabric is a plain weave textile of cotton and is designed using high count, fine yarns resulting in a silky, un-textured feel. The Poplin material is made with cotton, wool, rayon, silk, polyester or a mixture.
