They are incredibly easy to make. I knitted two flat pieces and then sewed them up leaving an opening for the thumb. They are also super quick to knit which is always a plus considering how lacking I am in patience!
This photo was taken by the recipient, the talented Heber Hanly. You can check out more of his photography on his blog.
I also found this absolutely charming knitting-related video below. I have never seen anything like it before. It's truly fantastic.
Have a wonderful day.
