There are plenty of YouTube videos regarding this, Try searching YouTube for "Marko Lathering Method".
I find a "scritchy brush" either a Pure or best/2band badger, or even better a Boar brush works well.
I soak my Semogue or vintage Addis Boar brush in warm water whilst showering, pop teaspoon of warm water on soap at the same time.
When I am out of the shower, I take brush from water bristles down and let it drain naturally, one gentle shake then load the brush as usual (having tipped water from soap) about 70-100 swirls works for me.
After loading, I face lather building lather. It starts off a bit thin and flies about the room a bit, after that it starts to thicken and develop until I have a face and brush loaded with really good, slick lather.
Think Perthshire has soft water, I know "my MWF lather is brilliant" replies are not what you ate after, but try this method? The boar brush certainly helps me on all hard soaps.
Mantic59 also has a few tips on his YouTube pages.....
