As others have commented, this is a difficult to follow tutorial. At about the 50 second mark a turn is taken and it was confusing. Again at about a minute and a half again the move is quite confusing. I was only able to figure this out by going into settings (the little gear at the bottom of the screen) and change the playback speed to just 25% and play and replay each difficult area multiple times. Confusion was introduced by constantly turning the partly constructed pot, I was always wondering if the corner I am supposed to be working on is a folded corner or a cut edge corner. Turning and turning the half finished project between steps just leads to confusion.
Correction: The second confusing part is not at a minute and a half, it is at 1:50 when starting to work on the third side. It took a lot of views to figure out that when the one side was folded in the front the other side was also folded in the back as it is not shown.
