The efficient method cuts one thread repeatedly and pulls the other out whole, rather than picking at every stitch from both sides.
The method.
One. Work on one side of the seam only. Slide the sharp point of the seam ripper under a stitch and cut it. Move along and cut every third or fourth stitch.
Two. Turn the work over. The thread on the other side now lifts out in one long piece, or in a few long pieces.
Three. Brush the cut fragments away with a lint roller, sticky tape, or a scrap of the same fabric rubbed across the seam.
What not to do. Do not use the ball end to plough along the seam. It works on loose seams and it cuts fabric on tight ones, and the damage is invisible until you press the piece.
Keep the ripper sharp. They blunt, they are inexpensive, and a blunt one is what makes people force it.
On overlocked seams, cut the needle threads on the underside every few centimetres and the looper chain lifts away in one piece.
On triple stitch or very short stitches, work in short sections and accept that it will take time. There is no fast method.
Press afterwards with steam. Unpicking leaves needle holes and a distorted seam line, and steam closes most of them on natural fibres.
Consider whether it is worth it. On cheap fabric, recutting the piece is sometimes faster and always gives a better result than unpicking a badly damaged seam.
Questions people actually ask
I cut a hole in the fabric.
If it is inside a seam allowance, sew a slightly wider seam. If not, patch from behind with a fusible mend and reinforce with stitching.
How do I remove overlocking?
Cut the needle threads on the underside at intervals — the looper threads then pull off as a chain, which is much faster than picking at them.
