Knitting scarves and caps has never been easier with Prym's knitting ring set. It consists of four coloured rings made of robust plastic measuring 13.5 cm, 18 cm, 23 cm, and 28 cm in diameter; a wool needle and a knitting hook for lifting and picking up the wool; and details instructions on how to knit a cap and a scarf. The plastic pegs have notches on the outside that make it easy to lift with the knitting hook. For an ideal mesh thickness, a yarn thickness of 5 mm to 10 mm is recommended.
