In the page's words:

In the heart of Bonn's old town, you can learn hand lettering or take part in a sewing course in a beautiful atmosphere.
Since 2015, made-in-bonn has been there for you with creative offers and more than 2000 course participants have already been infected by sewing enthusiasm and hand lettering. I look forward to seeing you soon! Until then, best regards from Bonn's old town
