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 Aug 8, 2016 and Oct 3, 2016 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Cardboard Contest 2016. 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.


When the winners are decided they will be notified and announced here on the contest page.
