|Part One: When I run out of empty bobbins, instead of throwing away the left over thread at the end of a bobbin when I need to use a new color, I am now winding the left over couple of yards of thread off of this bobbin onto an extra old bobbin from an old machine. Now I am saving my thread on this extra bobbin, to use for hand stitching and mending.
Part Two: I can repeat this whenever I want or need to onto the same extra bobbin (or two as you will see). This way, if I keep one extra bobbin of light colored thread and one extra bobbin of dark colored thread, (they will be layered on each other- lights on one and darks on another) my final “product” becomes two bobbins with usable thread which did not end up in the garbage can, again for hand sewing and mending. It is easier to wind by machine onto a bobbin than onto a spool, which is why I use the bobbins.
