Kos Tweed is a soft and light limited edition alpaca quality. The yarn contains 40% alpaca, 30% wool, 2% viscose, and 28% nylon. Yardage per 50 gram ball = approximately 150 meters. Kos Tweed knitting tension: 15-16 sts = 10 cm We have tested the tension on Kos Tweed compared to Kos, and there are small deviations. Kos Tweed does not fill as much as Kos because of the small bumps in the yarn. We therefore recommend doing a knitting test before knitting a whole garment.
