What is hard, is documenting a design so it can be easily replicated!
I am knitting hat 2, (version 2.1)--not quite the same as version 2.0)
Some details are refined, some techniques have been replaced with other ones (easier ones!)
I'm a few rounds into the brim--Knitting and note taking.. and they typing and correcting, and then knitting some more! Progress is slow.. but hopefully it will be worth the effort!
Not much to show for my effort right now.
