Needle Protectors - White Tulip These cute needle protectors reliably prevent your stitches from slipping off. They are simply placed on the tips of your knitting needles and keep your knitting project securely together, ideal for when you're on the go or taking a knitting break. The soft silicone protective caps fit all common knitting needle sizes and are also a decorative accessory for your knitting supplies. For knitting needles up to 2 mm (US 0), both needle tips can be placed together in one needle protector; from 2 mm (US 0), use a separate protector for each needle tip. Perfect for safely storing and transporting your knitting projects.
