This DK/Sport 4 ply yarn from Malabrigo is made with 100% superwash merino wool. Suggested US 4 to 6 needle or US E-4 to 7 hook. Each 100 gram skein is approximately 335 yards. This yarn is machine washable on the gentle cycle with cold water, dry flat do not tumble. Be sure to get enough yarn to complete your project since each bag is a different dye lot, and skeins may vary from bag to bag. Skeins may vary one from the other even within the same bag. To ensure random color distribution, work from two balls of yarn at once, alternating a few rows from each ball.
