I’m (Not) Ready for My Close-up Mr. DeMille

Here is the promised How-to Movie for deflected doubleweave selvedges. I have been trying to master iMovie, but I ended up having to decide between an edited version with abrupt jumps and weird pauses or this somewhat long-winded, unedited version. I would try again, but the warp I put on for the demonstration is all used up!

I would love some feedback on whether my explanations help at all.

Please no movie-making feedback because I am already quite aware of my lack of mastery . . . if you know how to join clips with audio in iMovie however . . . please, please let me know!
