Very straightforward. Use the file provided to cut out your squiggle! Any thickness of material works, but I preferred a slightly thicker (8mm) sheet of bamboo. Feel free to adjust the size of the squiggle to your liking.

I chose to paint the squiggle lots of different colors, making sure to paint the edges, as well. I wanted the squiggle to look a bit like a ribbon, so you can see in my example image that I tried to make the paint look like it is overlapping on itself.

I just used some double-sided adhesive to adhere the squiggle to the wall.
