100% Merino Wool This is the original Worsted that made Malabrigo an international favorite! A buttery-soft single ply of fine Uruguayan merino wool, this yarn is deliciously squishy and cozy. It’s also fantastic for felting projects! It is kettle-dyed in small batches by Malabrigo’s artisan dyers and is full of subtle variation. Great for hats, mittens, sweaters and more.
