The following eight steps detail how I made my TARDIS kite, in the hopes that you might be able to make one too.
Step 1: Materials
Seven 36" Dowels, ¼ thick
15-20 yards of extra kite string: For each section you lash together, you need about a yard. You only do that 15 times, but it's good to get extras.
2 Plastic Bags (Or you can use ripstop nylon! JoAnne's has it for $8 a yard, I will make another kite and show you what it looks like!)
Blue Spray Paint
Black and White Acrylic Paint
Spool of Kite String
