These exciting fiber kits can be used for felting or spinning. The ways to prepare these kits is up to you and your imagination. You can; card into a batt, blend the fibers on an art hackle turning the kit into roving, blend them on an artist blending board turning the kit into rolags, or spin them as they are. Each different prep will effect the way your yarn turns out---whether you want well blended colors or more of a chunky art yarn. Whichever way you choose these kits are a ton of fun.
