Over time, you do develop “callouses” from needlework. I had to get my fingerprints taken for permanent residency in Canada. They send the prints to the FBI to check to see if I am safe and legit. Anyhow, it took several tries to get good fingerprints for me. That is because over time, people who do needlework, cooking, etc. tend to wear their fingerprints off. The constant rubbing of yarn, etc. can wear down those unique markings. So, yes, we do create our own callouses or tolerances based on years of knitting, it is true! Also, some parts of your hand may just be more sensitive; the nerves are closer to what you’re doing with the yarn, something like that. This is real. 🙂

I totally have calluses from knitting – they don’t get big and rough, but they are definitely there!

Oh, yes, that callous I get on the “inside” of my ring finger, left hand, from holding tiny sock needles too tightly. (I’m working on that grip issue, but I do have to be consistent within the pair of socks.) I’m back knitting, not full time yet, but knit a few rows/rounds, rest/read, knit a few more, rest/read, repeat….. So yes, I do understand. My left index and middle fingers are not yet back to full flexibility or strength (nor are the other fingers/thumb or the wrist, for that matter) but I guess it will take much longer than the 6 weeks in the cast to regain normalcy. Neighbor said his hand has been through PT, etc., and it’s more than 6 months. Sigh. Well, at least I can knit again. I fully understand about sensitivity where it was unaccustomed yarn movement, too.
