I finished up the edging and collar on Mum's cardigan, and this is what I'm left with.
The pattern calls for 9 balls in the smallest size, and this is the end of the ninth ball.
Of course, I'm being disengenous. I bought an extra ball, as I am wont to do, and it will happily become a square of my Lizard Ridge.
I've been told by Denny (who is often quite reliable) that sales of Kureyon have gone up noticeably worldwide because of the popularity of Lizard Ridge.
Kudos to the designer.
