its so funny reading all of these- i also sew on a viking...and i love my machine but the one thing that (was) a problem was that dog=gone pressure foot going down all by itself!
(not that it does)
before my viking i had a brother- my chocolate lab insisted on laying right under me when i sewed- she was constantly (trying) to lay across my foot pedal--with the brother- not a big deal---brought that viking home and set it up---if i got up to walk across the room to the ironing board sure as... that dog would lay across that pedal and ZOOOOOOMMM down some seams (after all she weighed 90 pounds- she drove fast!)
it was a problem-
but one i miss- my poor ole dog had spent her 14 years with me- it's been a bit over a year now- and i sure miss her underfoot- and under my sewing table...and now that i don't have to (watch) that feature all the time i find it a great feature- i can hold on to the fabrics and know the foot will go down when i step on the foot. :)
