Periods make people uncomfortable – even in 2017.

From hiding a tampon up our sleeve as we head for the bathroom to speaking about our periods in euphemisms, many women find themselves taking measures to ensure we hide the fact we’re menstruating. And the issue is not restricted to misplaced embarrassment over a natural bodily function – the silence around this part of the female experience means problems such as period poverty, shame and even office sexism are a very real thing.

Which is why one female artist, Liv Strömquist, has taken the matter into her own hands by sharing her period-themed artwork across Stockholm’s subway as part of project The Night Garden – which also features birds, cats, trees and naked men.

Inspired by the ‘pastoral idyll’ genre, Strömquist wanted to provide some calm to stressed-out commuters, according to The Guardian.

The artwork features various women drawn in felt-tip pen, rendered in black and white with a burst of red highlighting the fact they’re menstruating.

All of the artwork spread out across Stockholm’s Slussen station for the past five weeks – also known as the world’s longest art gallery – shows women ice-skating while menstruating. From a lady ice-skating and lifting her leg to show she’s on her period to a woman just sitting down and brilliantly showing her period stain on her trousers.

This period-themed art is causing outrage on Stockholm’s subway
