Why are notches used in patterns

But thank you for your thoughts, I will remember them when sewing a pattern with included seam allowances the next time. Funny, I always notched out until reading somewhere last year that it was less accurate. All you have to do is find a way to mark your fabric that holds on long enough while you sew your garment…and does not stay afterwards. My mom was an outward notcher, and so have I been.

And… with wanting to serge edges before seaming, both notches and clips get obliterated. How do I solve this problem? Or is it not the usual thing to serge edges before actual construction? I always felt that it marked better and it would weaken the material to notch in.

I also take my time to pin on the patterns carefully in the best material saving way. I also carefully cut out the pattern as it is my guide to straight stitching. It has served me well over all those years. This is exactly how patterns used to be. This was before there were multiple sizes on one pattern. I think that it is too confusing to show it this way.

I always use a colored pencil to draw on the correct size and color OUT the notches. Not notching related, but hole reinforcer related. I recently came across a pattern where the student had backed all of her paper pattern with light weight fusible interfacing so that it would last as she intended to use the pattern many times. It looked very neat and made the pattern much less fragile whilst keeping it thin enough to easily get pins through. This technique could also make cutting out slippery fabrics slightly easier too.

The big four pattern companies always show the notches out. I run into problems with the inward notching when you have to stay stitch. The thread runs through the notched hole. Thank you for raising the question! I love hearing how we all have different techniques that work for us. I posted this same question on my blog and the concensus was to notch outward.

A good discussion! I was taught to notch outward, but somewhere along the way got lazy and started snipping. Thanks for the reminder of why I did it and should start doing it again! I notch outward. But instead of doing the extra drawing on paper, I simply draw my notches outward with the tailor chalk or a fabric marker onto my fabric. That seems to be less time consuming than finding extra pattern pieces to draw a simple triangle.

I am a theatrical costume designer so I use a LOT of patterns over and over. I usually trace them onto pattern paper so that I can keep the original in good shape. I always cut my notches outward. I agree with you it makes them more accurate when lining up the pieces. I love your blog by the way. It is very informative. Your email address will not be published.

That is so clever! Will definitely do that next time! Thank you. I always notch outwards too, and join the double and sometimes treble notches as you do. Great tip with the hole reinforcements too.
