The yarnDispenser by Yarn Valet is designed to hold yarn and twirl to release the perfect tension while knitting or crocheting. It keeps your yarn clean and tangle-free. Just place a ball or skein of yarn on the dispenser and as you knit or crochet the yarn will twirl and release just the right amount of yarn. Additionally, there is a 4" in/cm ruler on the base to check gauge as your go. There are also holes to hold your stitch markers and a pattern holder slot. The rubberized bottom will keep the dispenser from slipping on smooth surfaces. This lightweight dispenser is perfect for travel or keeping next to you on the sofa.
