Re: What do you NOT like about wool?
It takes more time. Washing and lanolizing wool isn't difficult, but it is a little something extra that I normally wouldn't have to do. When I used wool in the past during busy periods of my life, I would often leave dirty wool lying around for weeks before getting around to washing it.
Wool is an animal product and isn't always produced humanely. I have a few wool products, but I limited myself to purchasing used ones for this reason.
