What to do with a small hank of wonderful, but expensive alpaca yarn! We purchased the yarn, and had to design a vest around the one skein we had. This was fun to do! It also uses other hand spun wools, integrating the alpaca colors in the center for a special design. To change sizes, we changed needle sizes. For sizes 38 to 44 inches, and knitting needles sizes US #7 and # 10, or # 8 and # 11.
