Quarter-Inch Seam Allowance

How to Use

Heather explains that the key to marking the quarter-inch seam allowance on your machine is to use a product that has some height to it. Believe it or not, Heather recommends using bunion pads and explains that moleskin can also be used. Heather shows how to begin by first cutting a straight edge along whichever product you are going to use. Moleskin can be found in larger square sheets, whereas bunion pads are generally round. It is always a good idea to ensure a straight cut before adhering it to your machine.

Heather shows how to use your ruler to measure a quarter-inch seam allowance distance from your needle. Even if you have a marker on your throat plate, you should still measure to ensure accuracy. Once you have measured, you can place your moleskin or bunion pad on your machine.

Test your seam allowance on a scrap of fabric before starting a new project. It is also a good idea to stitch using a scant quarter-inch seam allowance for most quarter-inch seams because of the small amount of fabric that gets “lost” in the seam when it is opened and pressed. The bunion pads and moleskin will stay in place for a long time, but can be easily removed from your machine if you choose. While having it in place will help you stitch any quarter-inch seam allowance, it is especially helpful when stitching long strips.

This was good information On placing this quarter inch helping aid. I use a foam double sided tape but keep it single sided by not removing the green upper portion protecting the tape. I had been placing it closer to me and not directly on the plate but I will try this method of placement and the scant quarter inch. Thanks for the tip
