After more than 3 decades producing American wool yarn, Jaggerspun closed their doors in 2025. As such, ALL SALES OF JAGGERSPUN YARN ARE FINAL, and we will try, but cannot guarantee matching dyelots. 

100% Superwash treated Merino Lambswool in solid and heather shades works up beautifully for all those special projects you have in mind. Garments made from this yarn will not shrink or fade. Mousam Falls will retain its integrity after myriad machine washings and dryings. Machine wash using warm water and any laundry soap or detergent. Tumble dry.
