At this site http://stonearabie.com/Yarns.html can be found a variety of unusual yarns. Can any of you bonnet knitters tell me if any would be suitable for making a bonnet? I'm sure they could all be knitted to a bonnet pattern, but can they be fulled? Whereas I believe the Lairds amongst us might jump on bonnets made of mink, I on the other hand am interested in yak. If I recall my Asian Studies correctly, yak hair is sometimes an ingredient in felt items made by herding peoples.
