Great for unpicking seams, trimming threads, cutting buttonholes and undoing embroidery.
If you are anything like me you will always be misplacing these, I like to have a few around so I have plenty to choose from. This handy pack of four should solve the problem they are in lovely bright colours too, making them easier to see amongst all the mess (sorry work in progress)!
Why not keep one in your workroom, one for classes and have a couple spare!
