I have another magnet bowl tip.
I have some oblong ones about 5X8". I also have some grey steel shelves from when I first started Joyce's Workroom.
So I stick these long ones bottom side to the top shelf edge and keep special needles, tiny shears, thimbles, any thing that I don't want to get lost in the shuffle.
Now I know where my curved needles will be found. It's good for that little screw, nut or washer, that you don't know yet where they came from.
