The joining of two or more pieces of material is called?

A seam connects two or more fabric pieces together. When sewing clothes or crafts, seams hold the material in place. Stitches create the seam by going through both pieces.

Satin is a type of fabric, not a joining method. Stitch is one loop of thread. Binding finishes edges. A seam is the complete line where fabrics join.

Seams are used in making clothes, bags, and home items. They give strength and shape to sewn projects.
