I designed this hat to be a tad large. My husband has a big head, and my daughter and I have big hair. i designed this hat to have enough ease not to crush my hair.

  For those of you who have smaller heads, or hair that is not as curly. I suggest going down a needle size to make you hat accommodate your head size. 

 This pattern calls for Bernat Baby yarn for the windows. I like this yarn because it is reflective so it makes the TARDIS windows and light pop. You can use any white you want. Because this yarn is  a lighter weight yarn I doubled the strand for this portion. 

 This pattern can take any  worsted weight yarn as long as you have the proper TARDIS blue. 

I am a Whovian so I have a lot of TARDIS blue so apologies for not giving you specific yarn.
