Hi,
I struggle with sculpting a lot but the cloth brush a little down in the posts seems epic. The lead sculpting developer(Pablo Dobarro) at Blender is implementing this brush that with just a few strokes makes cloth look realistic.
I think it will make a whole lot of the cloth sim uses mute in the future.
