We invite you to join a global project to create fabric masks that promote hope, humanity, and hygiene practices in time of crisis. Collaborating across borders, we want to raise awareness about the risks of COVID-19 infection and the need for physical distancing and self-isolation, while advocating solidarity with the most vulnerable in our global community.

Kiss and smile at a safe distance!

The project offers instructions in many languages for how to make masks in individual sizes at home. All you need are materials you will likely find at home: a cotton T-shirt, a kitchen cloth, and non-woven fabric. You do not need a sewing machine; scissors, thread, and needle will be enough. The masks are washable, have a nose clip, and allow you to insert a replaceable filter, such as a surgical mask. While the Co-MASK cannot prevent an infection with the Coronavirus, it offers protection from larger droplets and prevents you from touching your face. Suppression and self-isolation are the only measures proven to protect the larger community!

We hope to inspire you to create these masks for your family, friends, and your community to advocate self-isolation, hygiene, and heartfelt human connection. Please wash your hands and the masks before disseminating and be careful to distribute them without direct physical contact. Feel free to download / use our free graphic kit with illustrations explaining the safe use of masks and other hygiene practices (free for use under CC license).

Create your own mask with a kiss and a smile, post it on social media with the hashtag #CoMASK
