I came across this video on YouTube... this is of a woman, Rachel John. She shows how she preps and then knits with 1,000 strands of yarn at once! She uses what looks to be stripped, pointed and varnished logs as her "needles". It is simply amazing.
Even if you are not a yarn crafter or a fan of fiber arts, you probably can appreciate the mechanics/engineering/preparation involved in this whole setup. Simply amazing to me.
