I got the Sew-Classic order today. (And an out of stock item was taken off of the order and the needle plate marking stickers were put in instead with no charge. I am happy. I meant to order those stickers too but forgot.) So far the emery cord has been good for a lot of things.
I smoothed out needle dings from the needle plate,
took off the partial stripping from the needle plate screw heads,
removed a sharp edge from inside my pinky ring,
almost tried to sharpen my seam ripper before I thought about the ring and what it meant as far as putting a sharp edge back on something,
and told the cat to stop trying to bite the cord and run away with it.
It is useful.
Sadly I also got bobbins to match a machine but I lost the auction after the order went out. Is there a thread for whining about the wish list or the ones that got away?
