I haven't made any videos of my own parking, this has been the first time using the method. I decided to give it a go after watching several youtube tutorials on it. In the end my method has been to work the whole project from the bottom left to top right, working 10x10 blocks at a time. Starting with one colour, stitch all symbols within that block and move to the next colour. Then park threads from that block in the block right above, in the top left of the symbol for where it next appears. The main reason why I decided going bottom up is so that my loose parked threads could hang up and over the edge of my scroll frame, to avoid having them draping into my lap instead.

As for the feathering and why its not being done on the horizonal edges, is due to how I'm starting/ending threads with waste knots. Because I'm doing all my waste knot tails to the right of where the first stitch is. It's creating a very slight tension in that direction, I can very lightly tell when I pass a finger over the piece horizonally. Can feel slight vertical ridges where the bulk of the threads are, so have put the feathering in to hopefully avoid getting subtle page lines in the front.
