yes you can. the walking foot has the same wide opening as the other feet. I move mine all the time (Bernina 1090). sure the new ones must be the same. one shift to the right with Bernina usually works for 1/4".
but the best test of your seam width is still to sew 3 pieces (1 1/2" w x 4" long) together on the long sides. press carefully. should measure 3 1/2" wide. adjust by making smaller or larger seam by how this turns out. if it is less than the 3 1/2",you are taking too big a seam. and if it is more, you are taking too small a seam. using fabric that is your project.

If you have a 1/4 inch foot, and all your seams are the same size. it doesn't matter if it isn't exact, it will still be close enough as long as your seams are all the exact same size that is close to 1/4 inch

Sorry, that's not true. Certain patterns require scant 1/4" and to be extremely accurate and have your blocks turn out perfect the scant 1/4" is very important. As someone else said, simple patterns a general 1/4" will be o.k. But the more complex the pattern, the more necessary an accurate 1/4" or scant 1/4" is.

My Viking does a perfect 1/4" if I remember to move the needle.

They always break on me. Plastic, metal, whatever = toast. I've gone back sticky labels marking my SA.

My Bernina machine came with a really accurate 1/4" foot. I use it all the time for piecing.
I also have an older Baby Lock (about 13 years old) but I have to use the lines on it. Therefore I don't use it for piecing.

Bernina # 57 is a perfect 1/4" foot has a guide WONDERFUL FOOT.

Sugar, I have a foot on my Janome and it measures a pretty exact 1/4 inch on the right hand side of the needle. As long is this is used throughout piecing your patches it will be quite accurate. Until you get used to it, use a piece of tape on the right side and before you know you won't need it. God bless and Merry Christmas. Quilting Joan

I second this one .

How do you bump the needle? Mine is off some since I had it serviced and I can't for the life of me figure out how to move it. Surely it's not that difficult
