Then I attached the general purpose zig zag foot. The slot in the foot matched the slot in the Necchi needle plate
Next, I attached the straight stitch foot. Same result - the hole in the foot matched the hole in the needle plate and the foot covered the feed dog perfectly. But, does the needle come down in the center of the hole in the foot? Yes, it does - perfect.
Then, I attached the zipper foot. I prefer the old, adjustable zipper feet because I can adjust the position of the foot in relation to the needle but this is the style of zipper foot that comes with new machines, now, so I guess I'll have to adapt.
The item I sewed with the zipper foot was welt to go on a small chair I am recovering. The shape of the zipper foot did not allow me to sew close enough to the cord to make a smooth welt but moving the needle to the left position did.
Hopefully, it would perform better on a zipper.
I didn't try the remaining feet because I figure I would never use them, anyway but I expect they would perform just a well as the feet I did try.
I will place a few of these sets on my next parts order to see if other folks like them as much as I do. It sure makes changing presser feet much more pleasurable.
