Getting a precise quarter inch seam is especially important in patchwork and the quarter inch foot aims to make it easier. It is a very simple but effective foot that allows you to keep a uniform distance by keeping the edge of the fabric against a guide bar as you sew.
Attaching the Quarter Inch Foot


It really doesn’t get more simple. Position the needle centrally, and place the fabric up against the bar. As you sew, keep a gentle pressure on the fabric towards the bar (too much pressure and it will fold over, or not enough pressure and the fabric will drift away).
What are all the Markings?

The markings on the foot are all measurements to help keep your sewing position as accurate as possible. Obviously the distance between the needle to guide bar is 1/4 inch, but what about the others?
Needle to the edge of the right side of the foot is 3/16 inch
Needle to the edge of the left side of the foot is 1/8 inch

Needle to first side notch (N.B. this is offset and on the smaller part of the foot away from the others) – 1/4 inch

The foot is the quickest, easiest and most foolproof way for getting a good accurate quarter inch seam on normal fabrics.
The first quarter inch side marking on the narrow part of the sewing machine foot is fantastic for knowing when to start turning the fabric when you get near a corner. Simply stop stitching when you are level with that mark, leave the needle down and pivot the fabric before you start sewing again.
If your pattern tells you to sew a scant quarter inch seam, then this means to sew just short of quarter inch. Generally this is considered to be about a pencil’s line width difference. It is to allow for the small amount of fabric that is always lost when pressing a seam open. This means you would have to keep your fabric just short of the guide.
You cannot change the needle position out of central for this foot. This is great in that it makes sure you can’t accidentally leave it in the incorrect sewing position. However, if you want to quickly zigzag over an area to reinforce it before continuing your straight stich, you would have to change feet.
If you are sewing something with texture, for example cuddle fleece, towelling or fur, then the fibres have a tendency of getting caught in the guide bar. Sometimes I will still use this foot if I really want accuracy but I will sew slower and keep a close eye for any signs of catching. Otherwise, a roller foot is better suited.
It is not ideal for sewing with the guide bar over the top of another fabric as the corner of the guide bar may snag on the fabric and damage it. Therefore I would always switch this foot out before moving on top of fabric to sew.

If you are using a different foot to get your quarter inch seam because of the fabrics you have chosen, then simply clip this foot to your machine, place masking tape on the machine flush to the outer side of the guide, and use this as a marker to help guide you when you change feet. Double check your placement with a ruler to the needle if required.

Some machines struggle more than others at the start and end of a line of sewing, especially on small pieces of fabric. This can be because the feed dogs are pulling at the fabric unevenly where the whole area of the feed dogs aren’t covered. You can reduce this by starting on a piece of scrap fabric and running straight onto your real piece (remembering a couple of backstitches or stiches on the spot or it will unravel a little after you snip the thread to separate the fabrics). Once you get to the end, simply do the same – a few back stitches then stitch over the edge of your fabric and finish on the scrap.
