Thanks for putting up that link Wrenkins, I have yet to learn how to get links put in a post. I watched this Youtube video back in 2017 and was thoroughly impressed with the presentation and of course the gadget in question, and of course I now have this Clearance Plate in my accessory box - a wonderful, yet so simple way of riding the bumps, and by showing this on a double hem pair of denim jeans showed this to perfection.
In the past I made myself a little felt wedge and this has worked, but I do like the Clearance plate that has both a thicker and thinner side - we should all have one.
