A 3000 year old ball of year was found in England. If that ain’t the cause for knitting better quality, hand knits with high quality yarn. I don’t know what is?
Can you image joy of an archaeologist finding a site with unseen items only to find a ratty sweater or an unfinished project in cheap yarn…ugh!
That ball of yarn will speak volumes of how we lived. I better get my stuff together!
