Ravelry user Nyss Parkes offers up a free pattern for this rad crochet TARDIS.

Very simple crochet pattern for an amigurumi TARDIS from Doctor Who. If you haven’t tried amigurumi or are new to crochet this could be a good place to start.

She also has a pattern for a mini TARDIS, perfect for hanging on your Christmas tree. [via Gimmie Gimmie Amigurumi]
The TARDIS pictured above was stitched by Ravelry user, Gatchan, using Nyss’ pattern.
