The workshop

Our workshop is located in the former DMC factory, an emblematic industrial site built throughout the 20th century, in the heart of Mulhouse.

It will have taken us more than a year to complete the whole construction: from the electricity and the floor, to the construction of a full mezzanine. To help us achieve them, we were able to count on the support of Ulule contributors as well as a grant from the Region Grand Est. In September 2019, we were finally able to settle in and open the workshop to the public.

We have a shop part to allow the public to come and get our mandrakes, masks, cosplay accessories and other decorative items directly from the creators.

The workshop also allows us to greet cosplayers and other handmade enthusiasts for training (molding, chain mail, papercraft, etc.) or for craft sessions with other enthusiasts.

Feel free to visit us !

HELLO ! We are Marie and Maël, a couple of passionate cosplayers, better known as Black Owl Studio.

Quick history

  • We started cosplaying in 2012, creating costumes  and using various techniques that we learned as autodidacts.
  • With our colleague Joris, we left our jobs as graphic designer, web designer and web developer in August 2015 to dedicate ourselves to cosplay and the creation of our company.
  • In October 2016, we joined the Hopla structure, a business incubator in Mulhouse in order to test our “life-size” activity. We settle in an attic converted into a workshop to make our costumes, accessories and objects.
  • Our Etsy store was born in March 2017, allowing us to market our creations everywhere in France but also across the world, whether in Germany, the United States, or even in Australia or Japan!
  • August 2018: The company Black Owl Studio (SARL) is born!
  • Our new workshop opens its doors to the public in September 2019.
