There’s no doubt about it, projects that are completed using hand spun yarn are simply beautiful. It is easy to see that the blanket or sweater is hand-made. Stores that carry hand spun materials are required to label the package so consumers know what materials they are buying. When shopping at flea markets and craft shows, skeins of yarn that have been hand spun and items made with this type of yarn are not often labeled. It is important to ask the vendor about the materials that have been used. Yarn can be spun using a variety of materials. Often lamb’s wool is used, but those who spin yarn have also been known to use silk, horse hair, and even human hair. Allergies are important to keep in mind.
