I missed the hotkey to stop the timer, but from going back and pausing the video as close as i can to the hat being crafted, I believe it's a 28.38 To skip over 2 minutes of character randomisation, skip to 2:40

Moderator note: Rule “must explicitly identify human leather hat on screen” was fulfilled by wearing the hat almost at the last second. Start time: 2:43:0@30, End time: 3:11:2@30 Total time: 842 frames @30 fps
