Thread Keeper ORT catcher.
Since I started using a thread keeper I haven’t lost any of my loose threads, either sewing a kit or a freehand design.
It folds to approximately 4inches x 6inches which makes it the perfect size to fit in a project bag. When it is open (8 inches x 6 inches) it’s big enough to store all the threads that are in use with a project. You can even store the needles you are using as they pin to the felt nicely.
It is made with quilting cotton with a wool mix felt inner and a popper fastening.
