Hi! I have never knitted with wool before and while I have knitted socks, I have only knitted socks for babies and toddlers (only people who couldn’t complain if they weren’t quite right - LOL!) Does anyone have any tips for working with wool and sizing wool socks? I have a book with measurements for men’s socks but do I need to adjust the size due to the wool - especially after I wash it? Thanks so much! 
Knitting men's woolen socks
How many you cast on and the needles you use all depends on the yarn weight. If you’d like patterns I’m sure we can find you all you want. 
BTW -I’ve made several pair now and the only ones that have held up have been the ones that are made with actual sock yarn which has wool and nylon/polymid/whatever in it for strength. I also will only use superwash wool. 
Even if it is superwash wool, I’d do a long swatch, measure it. Then wash & dry, and recheck size.
I used to handwash all my wool knit socks. But discovered that they would find their way into my laundry basket & get tossed in with the wash. So now, I just plan to have them go thru the washer & dryer in the first place. They do shrink some. I’d say about 1/4-1/2" lengthwise over the total foot length. Widthwise, the snug up too. But if I adjust for length, then I’m fine.
Nylon in the blend makes them more durable. They don’t wear thru at the bottom of the foot as fast.
I put them in a laundry bag so they don’t catch on zippers or whatever, but they do go through the washer and dryer. I don’t think I’ve noticed shrinking, but they tend to stretch out a bit so that’s probably a good thing unless you made them too small to begin with.
