Do you have a library of beautiful pattern books with no yardage information included to help you make informed yarn substitutions? Our Yarn Info Finder's aim is to provide you with as much information as we can about yarns used in pattern books in current circulation. Below is a list of yarns we have found gauge, yardage, and ball size information for. Whenever possible, we have also included fibre content and needle size information too. Just click the plus sign beside each yarn name below, and yarn substitution information will appear.
