Although it is difficult to completely define and categorize yarns and fibers, I am going to attempt to focus on two main categories. The first category is made up of qualities that are mainly fiber-specific (wool, nylon, etc). The second category is made up of qualities that are specific to individual yarns (Berroco Comfort, Lion Brand Wool-Ease, etc). These charts are not going to be exhaustive (there is so much information to be gleaned through experience!), but I hope that they can serve as a preliminary guide.
Today's chart focuses on fiber-specific qualities with another chart to follow in my next post.
