Starting at one end of the seam, match the corners and pin them together.

Work your way down the edge to be sewn, pinning the two pieces of fabric together.

The closer the pins are, the more stable their hold will be. However, you will have to stop to remove each pin as you sew. For a beginner's skill level, space the pins an inch or two apart.

Continue until you've pinned the two pieces of fabric from corner to corner.
