I have the metal seam guides for the featherweight,my new janome 6300p came with one also. euro-pro has a foot with a adjustable seam control. DottieBug

I forgot to mention I also have a magnetic seam guide that can be used on any of our older non computer machines.

One of my FW's was really slow when I first got it so I made an adjustment inside the foot control and that fixed the problem.

There is lots of help, on the internet, so that they are easily maintained at home.
