I used to be so scared at the thought of having to unpick my overlocking, but it’s actually pretty easy. I’d almost say it’s as easy as unpicking a regular sewn seam. Like everything, I’m sure there is more than one way to unpick a serged seam, but this is my favourite.
Below you can see the two needle threads running horizontally and the upper looper looping in between them vertically. To unpick your serging, you need to focus on the needle threads.
Start by sliding your unpicker underneath the two needle threads. Take care to avoid the looper thread. Push your unpicker through to cut the two needle threads.
Repeat this every 3-4 stitches. Above you can see I’ve done it roughly every 4th stitch.
Once you have gone all the way along your seam, put the unpicker under the looper threads and pull it up to loosen them. You don’t want to cut them.
Once you’ve loosened the looper thread enough, pull on it with your hand and the whole seam will come undone!
If it gets stuck along the way, try giving it a harder tug. If it’s still stuck, use your unpicker to loosen the stubborn section.
Here’s a little video of the fun part…
Not so scary after all. Do you have a different method you use?
