The Marling Helper works like a portable yarn bowl...without the bowl. It helps keep various yarns separate and untangled when you’re working with multiple strands at the same time to create different textures or colors in a pattern - a process known as marling. Katrinkle's Marling helper comes with a cute little hook you can use to pull the yarn through the holes. Knit or crochet as usual, and the tool sorts out your yarn for you as it gets to your needles or hook. Product Details: Material: Wood & Acrylic Approximate Size: 2.5” x 1 7/8” x 1/8”
