My first-born was dating a thoroughly delightful fellow Whovian, so I made her a purple Dalek (her favorite color) using Amdowns pattern for Christmas 2009.
Then the husband wanted one, but it had to be "accurate" so I made him select the yarn.
Next he suggested a Cyberman...but I had no idea which version so I just snagged bits & pieces from 1 - 8 that I could manage & gave it to him for Christmas 2010(even though the sons still haven't made the weapon he's designed to hold! Maybe over summer break...).
Finally got around to making a Tardis.
Knitting does not come naturally to me, so this was rather challenging, to put it politely.
