I have a pfaff shelf sitter
My #3DD talked me into getting one long ago..I used it alot for rolled edges on veiles, even quilts.etc. My#2 DD borrowed it to make a wedding dress etc. brought it back with missing parts, etc. I think once in awhile I should get it down and see if I could get it working again. Threaded it by the method lipswing uses..writing down the tension settings, before moving them.. new ones I have not even looked at. wishing gets to be a dead end so I try not to burden myself with longings not to be fullfilled..
Happy sewing!
