This fingering weight yarn from Malabrigo is a single ply made from 100% Superwash Merino Wool. Suggested D3 to 7 hook or US 1 to 2 needle. Each 100 gram skein is approximately 420 yards. This yarn is machine washable on gentle cycle with cold water, do not tumble dry and dry flat. 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.
