7V is quite hardy and we've got socks that have seen a LOT of wear made from it, plus it's fine for gloves and the like as well. I wouldn't make a garment or even a hat out of it because it's a bit itchy, has a tendency to stretch out over time, and pills a bit too much. I've used a couple of similar yarns that were slightly better quality over the years, but they were also notably more expensive, so... it's still a good deal. Especially if you're making basic boot socks.

The apple of my eye right now is this sweater my wife recently made me with a bunch of fat worsted yarn that we bought at the local sheep & goat fair. It's made from raw undyed wool of a rare heritage Finnish sheep breed called the Kainuunharmas that all have the same color - born black and gradually get whiter, with the coat being variegated as well. They get the different shades of grey yarn just by mixing the different parts of the coat differently... I had a hard time picking which shade I wanted too, haha.

Tukuwool is on my list too, but we've pledged not to buy any yarn without choosing the project for it first while we destash.

Oh and PS. thanks for the offer, will keep in mind!
