I have that same battery operated bobbin winder, that doesn't work right!! :D But it does give my grand daughter something to do, when she comes to visit!! :D After she leaves, I rewind them on my machine.
My favorite sewing item is a very old cloth pin cushion, that a friend of my Mother's made for me. It's tattered & old, but it is special to me!! My next most used item is my seam ripper. My husband gave it to me over 40 years ago & I still have need to use it quite often!! Oh, the memories!!
:D :D :D :D
