I would say for full time wool you could get by with 5 pairs. Ideally I like to have 7-10, just to allow for some variety and time to wash if necessary. In reality we have more though, as we just love wool so much and then they do not wear as quickly

Also, crocheted wool works great as soakers. It just depends on the look you prefer. Some people prefer knit, some prefer crochet. I knit, so most of ours are knit, but we do have some crochet longies which I love too!
