Cardboard is so plentiful that we often overlook it and throw it away. Instead of bundling it up for recycling, grab a box or two and see what you can create for the Cardboard Contest! Prizes for this contest are graciously provided by Howtoons!

Tape, cut, score, and construct your way to the top and you could win a Howtoons subscription and Canon PowerShot camera! It doesn’t matter how you use the cardboard, as long as you incorporate it into your Instructable you can enter it for a chance to win and be King or Queen of crafting with cardboard!

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Mar 13, 2017 and May 8, 2017 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Cardboard Contest 2017. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.
