How to Sew a Basic Seam

Threads

Seams play an important role in giving your garment its shape. They connect corresponding fabric edges that are cut and marked from a pattern and hold the garment together. Before you learn how to sew a basic seam, find out about the three parts that make up a seam: the cut edges of the fabric, the stitched line, and the seam allowances.

Mark and align

Patterns pieces are marked with notches to help you align the fabrics before sewing the seam. Find out one easy way to mark the notches on the fabric. Then see how to prepare to sew a seam aligning the notches and fabric edges and then pinning them together.

Secure the start and finish

You can choose from three methods to secure the beginning and the ending of a seam.

Important steps after stitching

After you’ve sewn the seam, you can pink the seam allowances to prevent the seams from fraying.

Be sure to press seams as you sew, for better-looking results. There are a couple of way to press the seam allowances, depending on the pattern instructions. Garment sewing expert Judith Neukam demonstrates the ways of pressing along will all of the other techniques noted.

This detailed tutorial is one video in the comprehensive Teach Yourself to Sew series.

You’ll learn about shopping for fabrics, choosing patterns (including selecting the correct size), and planning the perfect pattern layout. From machine-sewing simple seams to inserting zippers and stitching buttonholes, Judith demonstrates the key steps to making a custom garment.

Discover methods for clean-finishing seam allowances and applying facings so all edges are neat. To add shape to garments, Judith explains how and why to sew darts, and how to gather fabric for volume. Other garment elements, such as sleeves, pockets, and elasticized waistbands, are shown in easy-to-follow video tutorials.

Advancing your skills
