Crochet circles for staircase

My daughter has a yoga and dance hall with a boring staircase leading up to it. She wanted something bright, colourful and handmade for it. I decided to make crochet circles. Each circle is different.

Many more are needed because the staircase is high. But this is a good start!

Corner of the mirror:

A couple of photos of the room itself. My daughter loves just as bright colours as I do!

This project taught me also not to take anything for granted. The girls had glued some of the circles with the wrong side facing up. I had forgotten that if someone doesn't crochet, they don't know which side is right or wrong! But I didn't turn them, the paint would have come with them!
