How to Mark Notches When Cutting Out Sewing Pieces

When I was learning to sew, my sewing teacher always had me cut little triangles that poked out from the seam allowance wherever there was a notch mark on my pattern pieces. The problem with this, however, is that it’s really hard to put the triangle marks in exactly the right place, and even if you do, they won’t necessarily match up perfectly to your notch marks on the corresponding pattern pieces. Plus, marking notches like this makes the cutting process go a lot slower.

Alternative Ways to Mark Notches on Pattern Pieces

My favorite way to mark notches is to cut out all of the pattern pieces and then go back and put a small cut into the seam allowance where the notch is supposed to be. This way I can quickly cut out all of the my pattern pieces without taking time to mark the notches as I go. The little cut shouldn’t be more than 0.25-inch into the seam allowance — it just has to be noticeable. You want to be extra careful not to cut so far that there would be a hole on the finished garment.

Cutting a slit in the seam allowance doesn’t work on all fabrics, though, because some fray too easily. When you are working with fabrics that fray, you can use a fabric marking tool to note where the notches are supposed to go. You can either place a dot or draw a small line to mark the notches on your pattern pieces.

It’s very important to mark the notches on your sewing pieces because it helps you line them up properly when you are sewing. Without notches, your sewing project can turn out lopsided or drape improperly. If you’ve always been tempted to skip the notching step, consider these time-saving alternative methods.
