Hmmmm I think I like the paper method a tad bit better than the finger smooch method... Ive had enough blue fingernails to last a life time with out trying... I've never set pressure on an industrial walking foot. I just went with what was on mine... It worked ok so I never messed with it. I've read that the heavier fabric needs more pressure - only thing I can think of is that it might have to have more pulling power in some cases...
