This gets to the very heart of garment construction. The difference is fundamental:
-
Sewing is the action or process.
-
A seam is the result or product of that action.
Think of it like cooking vs. a stew.
-
Cooking is the overall skill and process (chopping, frying, boiling).
-
A stew is one specific dish you can create using those cooking techniques.

Detailed Breakdown
What is Sewing?
Sewing is the craft and process of fastening or attaching objects using stitches made with a needle and thread. It is the broad, overarching term.
-
It is a Verb (an action): “She is sewing a button on her coat.”
-
It is a Noun (a skill/hobby): “Sewing is a very useful skill to learn.”
Sewing encompasses many techniques, including:
-
Joining fabric (which creates a seam)
-
Attaching buttons
-
Creating hems
-
Embroidering designs
-
Quilting layers together
-
Mending a tear
What is a Seam?
A seam is the specific line where two or more pieces of fabric are joined together by sewing. It is a single component of a larger sewn item.
-
It is a Noun (a thing): “The seam on the shoulder of this shirt is coming apart.”
-
It is the Result: It is the physical manifestation of the sewing process used to join fabric.
Seams are characterized by:
-
Their type (e.g., plain seam, French seam, flat-felled seam).
-
Their location (e.g., side seam, inseam, shoulder seam).
-
Their finish (e.g., serged, pinked, bound).

Example to Clarify
Imagine you are making a simple tote bag.
-
You sew the two side pieces to the bottom piece. This action creates the side seams.
-
You sew the two handle pieces to the top of the bag. This action attaches the handles, but it does not create a “seam” in the traditional sense; it creates an attachment point.
-
You then sew the top edge of the bag to fold it over and create a neat finish. This action creates a hem.
In this entire process, you are sewing. The seams are just the specific lines where the main fabric panels were joined together.
In short: You use sewing to create a seam, but you also use sewing for many other things besides just making seams.
