Welcome to Knitting Help!
Have you tried asking at nearby yarn shops? Often the shop owner is aware of other knitters or crocheters who would be interested or will keep your need in mind. Is there a knitting group at the shop? Is there a bulletin board at the shop you could post on? Have you searched online for knitting groups in your area? Joining those may be a way to recruit knitters. What about groups at senior centers
or appeals on Facebook and through Twitter?
