How to sew in a straight line
Watch the seam guide, not the needle. Line the fabric edge up with a mark on the needle plate and let the machine feed the fabric while your hands just guide it.
Pinny's tip
Practise on lined paper with no thread in the machine. The holes show you exactly where you wandered.

What you'll need
- Sewing machine: straight stitch, length about 2.5mm.
- Magnetic seam guide or masking tape: a raised or visible edge to steer against.
- Scrap fabric or lined paper: for practice runs.
Step by step
- Find the line on your needle plate that matches your seam allowance, often 1.5cm on UK patterns. Add a strip of masking tape along it if it's hard to see.
- Put the fabric under the foot with the raw edge against that line and lower the foot.
- Start slowly. Rest your hands lightly either side of the foot; don't push or pull.
- Keep your eyes on the fabric edge against the guide, not on the needle.
- Stop with the needle down if you need to adjust, lift the foot, straighten, lower and carry on.
- Backstitch a few stitches at each end to lock the seam.

Common mistakes
- Pulling the fabric through. The feed dogs move the fabric; pulling bends the needle and wobbles the seam.
- Sewing too fast at first. Most machines and many pedals let you go slowly. Speed comes later.
- Watching the needle. It feels natural but makes you drift. Look at the guide.
