How to Sew A Seam | Learn to Sew | Lesson #3

Seams are a mainstay to most sewing projects. Seams that have straight sewing and even seam allowances are a must for a professional-looking project. Find everything you need to sew a perfect seam here.

For this project, you’ll need fabric (I’m using 3×5 pieces of muslin for this – the perfect size for practicing), pins, thread, and scissors.   The key to a strong seam is backstitching! It’s always important to backstitch at the beginning and end of the seam. Backstitching on a machine is the equivalent of tying a knot while hand sewing – it locks the stitches in place. Without it, the seam can open up. This happens especially fast if the seam will be under any stress – for example, turning a project right side out after sewing.   Here are my steps to sewing on a machine:

The Process:

scrap fabric for test sewing

  • pin your fabric right sides together
  • insert the fabric under the needle so your seam allowance is correct and the edge of the fabric is 1/4 inch past the needle and pull the threads to the back of the machine
  • use the handwheel to move the needle down into the fabric
  • backstitch to the edge
  • sew down the seam to the opposite edge
  • backstitch for about 1/4 inch at the end

Optional: to finish the edges of your new seams, you can either use a tight zig zag stitch or you can use pinking shears to reduce fraying on the inside of your seams.   I like to press my seams with a steam iron after sewing because it makes them look a little neater. 🙂 You can also clip the edges with pinking shears to stop them from fraying – I almost always do that.
