I think i did it!
Took me almost an hours but i managed to get a half decent lather.. It seemed like i was not adding enoug water...
Sorry if I repeat myself: I sometimes get thin lather like this in the bowl, but try lathering a bit more on the skin (face or palm), as it gets much thicker for me when I do it. (Or just get rid of it if you don't think it is worth the trouble...) Remember Mantic's video recommend face lathering too.
