These cute Katrinkles Sheep Bobbins are great for fair isle color work. To use them, simply wind your different colored yarns onto the bobbins. This helps you easily access each color while knitting and keeps your workspace tidy. When it comes to maintenance, keep them away from excessive moisture as the birch wood might warp. If they get dirty, you can gently wipe them with a dry cloth. Also, store them in a cool, dry place when not in use to ensure they last a long time.
