In the Rainbow Contest, we're celebrating the rainbow: an ephemeral natural phenomenon that inspires awe and admiration in those that behold it.

Any rainbow-inspired project is eligible for this contest, so forget about limitations and get creative. After all, when it comes to rainbows, the sky’s the limit! There will also be a special judges' prize for dye projects.

The winner will take home some incredible prizes from Dharma Trading Co., including a heat press, screen printing kit, and light box.

We will be evaluating each entry based on ingenuity, clarity, creativity, and quality of presentation.
