I've also been finishing my Wattlebird sock.
This is the series of socks I'm working on inspired by the passwords from the Harry Potter books Wattlebird.is the first password found in The Chamber of Secrets. Harry and Ron arrive at Hogwarts in a “borrowed” Ford Anglia, meeting the Whomping Willow in the process. Ron ends up vomiting slugs after trying to curse Malfoy and then of course there's the voice that only Harry can hear. I've used these themes within the pattern of the sock.
Twisting snake cables.
Slug cuff detail.
A Whomping Willow.
The pattern was written and then given to test knitters. They knitted it and found my mistakes, corrections were made and then it was checked over again. This goes on for a bit until eventually everyone is happy.
Now the pattern is finished, the pictures have been added and it's available in my Ravelry store which means the whole process starts again for the next sock.
