Alright. I've made a thing. I also wrote down the instructions on how to make the thing. I do not often write out instructions. So they are what they are.
The plan is to make a step-by-step photo tutorial soon. That will give me a chance to make a less wonky example.

Edit to change the URL and link to the updated instructions with photos.
