Linework by Tula Pink for FreeSpirit Fabrics. Have you ever wondered what the design process looks like? Tula has laid it all out for us to follow along with the Linework collection. She has created designs showing the various stages of the design process; the notes, sketches, eraser marks and original ideas that eventually become the artwork we love. The Linework collection is Tula's thought process on cloth, with black and white animals and pops of her signature colors. 100% cotton fabric is great for sewing and quilting.
