Okay so this one is a less about Copenhagen and more about something that I love in general, in all places, at all times. For those of you that have yet to be converting bunting is triangles (made of fabric or paper or something of the sort) on string (or twine or something of the sort). It is gorgeous and is an essential item of home decor. True story.
I made some to put in my room out of free KU Copenhagen maps with twine as string and then they had some at Studenterhuset. It also contributed to the hygge in my life.
