Gauge is not important to this pattern. However, bulkier yarn will result in a larger finished piece.

Materials
TARDIS blue yarn- I am using Caron Simply Soft for this.
Darker blue yarn- for details
Black yarn- for “Police Public Call Box” signs
Optional: white yarn for “Pull to Open” and “St. John’s Ambulance” signs
Plastic mesh canvas- for the inside structure
Plastic from packaging- for windows, signs, etc.
Hook to match yarn size- I used a 4.25 mm G size hook
Yarn needle
Scissors- be sure these aren’t your good fabric scissors. you will use them to cut the plastic mesh canvas

I have a video tutorial available.
