Challenge: fill a 2D space with one continuous line doing 90° angle turns in the same direction (left/right)
Last night I was doing that in my head: filling a 2D space with one continuous line doing turns at a 90° angle, always in the same direction. Other people do this as well, right?
Well, today I actually drawn it:
I started top left, and finish bottom right. I turned right all the time. It took me about 20 minutes.
It was not so easy!
The difficult parts are:
- keeping the line straightly vertical or horizontal
- not getting stuck (because we don't want to make the line touch)
- not repeating the same patterns too much (though repetition of symmetrical patterns could be very pretty!)
Here are some mistakes I made (the most obvious ones): 
But anyway, it was my first attempt, and I kinda like the childish aspect of it. 10/10 would do again!
Show me your attempts in the comments

Note: I used a cotton canvas which cost me 1,50€, but you can just use a sheet of paper if you don't plan to show how good you are to everybody by hanging it on a wall.
