I really wish I could help you, but I have a similar black hole in my sewing area, as small as it is, the sewing area, not the stash. I can use a pr. of scissors or a seam ripper, put it down and it vanishes. I sympathize - as soon as you buy a new one, you will find the old one. I did this once with the clear cover over the bobbin case on my sewing machine, went into town, and picked one up at the dealer. A few days later, I found the old one, clear anything on my carpet disappeared into the blackhole, or should I say on top of it. Good luck.
