How to draw big circles / rainbows on walls or windows.

How to get the best big perfectly round circles or circle like shapes, like rainbows. Using string, masking tape and chalk (or any other drawing item like a pencil etc).
Excuse my West country accent (Bristol, UK). Also my heavy breathing, I'm still recovering from Covid. Even though it's been two months I'm still getting out of breath easily. also I'm sorry for the wonky filming 😂

A little too close to understand what your doing, would have been great for a big view of the wall

[@joshuaiowa2190]

You are not able to draw a descent circle with this trick. First make practice then make video.
