Why does my sewing machine not sew straight?

It is best to make use of a stitch plate for sewing straight. When your sewing thread is tightly pulled on the underside and an even stitch is not properly formed, then the tension in the top thread gets thrown off track. At times, lightweight fabrics also get tangled and drag down into the sewing machine.

To get a straight stitching, it is best to observe while you sew as the needle is moving consistently. Focus on the fabric and seam to guide a straighter sew.

Some primary issues for why your sewing machine does not sew straight:

  • Machine gets jammed
  • Machine skips the stitch
  • Looping of the thread on the bottom or top side of the stitched fabric
  • The bobbin thread pulls through the fabric’s top side
  • Bunching of the thread
  • Nesting of the thread
  • Uneven stitches
  • Breakage in the thread

Expert Advise: Make sure to thread a bobbin correctly to avoid any skipping stitches or bunching of the thread on the fabric that potentially damages the material you are working on. Also, after properly threading the machine it is recommended to test on a piece of scrap before continuing the sewing project. 

What is the best stitch length for sewing a straight stitch?

The best stitch length for sewing a straight stitch is 3-3.5mm. The most basic stitch employed in sewing is the straight stitch, and it is primarily used for joining two fabric pieces together with a seam.

Stitch length is the length of each stitch that is sewn with your machine. The stitch length is what controls the amount of fabric that is pulled in every stitch. 

A shorter stitch length means less fabric pulled while a longer stitch length means more fabric pulled through. Stitch length defines the amount of fabric packed into every inch of a stitch, resulting in a tighter or a looser seam. 

Shorter stitch, tighter the seam while a longer stitch gives looser seam. In other words, shorter stitch length gives permanent and stronger stitch while longer stitch implies temporary and weaker stitch. 

The best recommended stitch length for straight stitching is 3mm to 3.5 mm.

What are the settings for a straight stitch on a sewing machine?

Each sewing machine has slightly different settings, whether you have Singer or Brother sewing machine. Always review the manual beforehand and adjust the stitch settings and tension to create perfectly straight stitches.

In general, basic settings for a straight stitch on a sewing machine are:

  • Stitch tension to 4
  • Stitch length set to 3.5 mm or 10 stitches per inch.
  • Stitch width set to centered needle over the stitch plate.

A dial for stitch width moves the sewing needle right and left, set to zero for a straight stitch. However, this depends on your sewing machine. 

The dial should be such that the needle is at the center of the plate to achieve a precise seam allowance. The seam should be set about 5/8”-1/4” (16mm-6mm) seam allowance to get a straight stitch, depending on the indications on the pattern you are following.

Tools for Sewing Straight

Some tools include masking tape, washi tape, sewing machine slide or grid, foot guide, zipper foot, ruler, and attachable seam guide.

The following tools are helpful in sewing straight:

  • Edge/width of a presser foot: This will help you guide the stitch. It is advisable to set to ⅜ inches seam with centered needle position while ¼ inch seams with left positioned needle. Do not watch the needle.
  • Washi tape/painters tape/elastic: Mark the seam guide with any of these tapes to get a guideline on the machine’s throat plate. Focus on the tape while sewing and avoid watching the needle. This will also give you a uniform width as the fabric edge is lined.
  • Presser foot: Set the presser foot number to 1/16”, 3/16”, ⅛”, or ¼”. This will manage multiple fabric layers for a straight stitch.

Expert Advise: When in doubt, take time and sew unhurried. Slowing the machine will help you control the speed and stitch line more efficiently.
