This single ply DK/sport weight yarn from Malabrigo is made from 50% Mulberry Silk, 25% linen and 25% Merino wool. Each 100 gram skein is approximately 325 yards. This yarn can be hand washed in cold water and dried flat. Suggested US 4 to 7 needle. 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.
