Here's a surefire way to keep your seam allowance accurate.
The most important skill in quilting is being able to sew a consistent quarter inch seam allowance. No matter how accurate you are at cutting out your pieces, if your 1/4" is off just a little, your quilt top won't square up correctly.
Even worse, it's the kind of error that compounds with each additional square: If you're off by just 1/16" on each square, by the time you've sewn eight squares, your quilt is off by a full half inch.
But there's good news. Janome has a presser foot that's designed to give you a perfect 1/4" seam allowance every time. It's called the 1/4 inch Seam Foot O.
This seam foot has a little metal flange to the right of the needle along which you guide your fabric. To see this foot in action, watch 1/4" Seam Foot O Video: Perfect 1/4" Seams And Corners. In the video this foot is demonstrated on the Memory Craft 11000 sewing and embroidery machine.
The guide can also be used wherever a 1/4" seam is called for. It is especially helpful when the markings on the needle plate cannot be used, such as when completing a flat-felled seam.
There are a number of different versions of this foot, depending on your Janome sewing machine:
