For this Speed Challenge, make something out of cardboard!

Whether you use corrugated cardboard (like from shipping boxes) or single-ply cardboard (from cereal and food-type boxes), or cardboard tubes (toilet paper and paper towel rolls, or similar) – all projects that include cardboard are eligible.

There is a special Judges' Prize for the most impressive and creative use of recycled cardboard tubes.

Get crafty fast; this challenge is only open for two weeks!

The Cardboard Speed Challenge is closed.
