Sewing Shorts Tutorial: Sewing the Crotch Seam
September 29, 2009 sewing Comments OffMost sewing enthusiasts dread sewing the crotch seam on a pair of shorts or pants, but the method that I learned and will teach you here is really quite easy. I have found it to be the easiest method for sewing casual pants of any kind; shorts, pajama pants, or long pants. In fact, it can be quite fun and when you are successful with it the first time, you will be quite proud of yourself!
So far, we have covered cutting out the pattern pieces and sewing the inner leg seams of the shorts. Yesterday, we talked about sewing the outside, or side seam, of the pair of shorts, making sure that you are putting a front leg and a back leg piece together. When both the inner leg and outer leg seams have been sewn, you now have two separate leg pieces that need to be sewn together, which means sewing the crotch seam.
The first step is to turn one leg inside out, with the wrong side of the fabric facing you. Turn the other leg right side out, with the right side of the fabric facing you. Place the leg that is right side out inside the leg that is wrong side out and match the inner leg seams. Line up the fabric edges and you will notice that you have a curved seam that is in the shape of a large “U”. This is the crotch seam.


The picture directly above will not be a pair of shorts that anyone would actually wear. I just sewed together different types off fabrics to better illustrate how to sew the crotch seam. They really would be a crazy pair of shorts if actually worn!
In the picture above, the shorts leg on the right is inside out while the leg on the left is right side out.


In the picture directly above, you can clearly see the “U” shaped seam that has been pinned. (The green fabric was inserted for contrast so that you could see the crotch seam more clearly; it is not a part of the shorts or the crotch seam.)
After the crotch seam has been pinned all the way around, start at one side and sew around the curve, using a 5/8 inch seam allowance. When you are finished sewing this curved crotch seam, press open the seams as far as you can, starting at the waist. There may be more detailed instructions on the pattern you are using, so check those to see if you need to take any additional steps.

The next step is to pull one leg out of the other and feel really proud of yourself that you successfully sewed the crotch seam on a pair of shorts or pants.
The shorts are almost completed at this point, but there is a little more sewing to do. A waistline casing will need to be sewn, elastic inserted, and then the shorts will need to be hemmed. We will talk about the sewing the casing in my next posst.
