French Combing Wool

Wools that are intermediate in length between strictly combing and clothing. French combs can handle fine wools from 1.25:2.5 in. in length. Yarns that have been produced with the French combing method are combed dry; without oil added. The yarn is softer and loftier than the Bradford (worsted) yarn
