This Slub Knit Jacquard by Mind the Maker is a made an organic cotton fabric that is soft and warm with totally unique texture, reminiscent of ocean waves or mountains on the horizon. What is slub? It's when the yarn used to make the garment is thicker in some places and thinner in others, creating variation and visual interest in the final fabric. We love this fabric for the gorgeous texture, soft warmth, and incredible color options.
