I might not remember correctly, but have you shared som informative pictures regarding how to use the button hook?
We have not. It takes some practice but once you get the hang of it it goes quite smoothly, also the button holes breaks in and this also makes them easier to put on with time. Please email firstname.lastname@example.org for further instructions. Gabriel is more of an expert than I am.
Posting a video is not a bad idea, I hope we can make time to post something in the future.
