My ex used to weave so when my GF started dragging me around to yarn shops, I knew many of them and showed her others. That worked well. I loved that there is a yarn shop across from the Mayo clinic with a man's corner with chairs and magazines.
I walked into a trendy yarn shop in Santa Fe or maybe Taos. I got a glace from the three women who were knitting . It felt like . "no your wife isn't here, don't bother us." I was not appreciative. When one finally asked, Wat is your current project?' I decided I wasn't gong to be nice. "I don't knit." They all nod with "we knew that" attitudes. Then I followed up with, "I spin, what to you have in roving." They didn't have any. Can't have knitting without spinning. And I have been known to drop some serious money in a yarn shop..
Thanks for the info about the many types. . The project is in time out now.
