Great Job on the Vid. I've been trying to show some to incorperate this method.
I've done it on my Boot toes By Acenat, and I'm getting ready to redo my thighs and incorperate this same thing into them.
MY pics are in my build, but if you like I could post one here of the "Trenching" I did. I call them "M" cuts.
I'm not knocking you or anything, Just saying I use a similar method. Thanks for sharing.
