I use it for a lot of the above as well as holding my "Angler 2" in the right position on my machine. I can stick it over and over again.
Marking the 1/4" stitch on my old machine.
I use it also to hold loose threads but also will use it to pick up small threads off of my fabric after using the seam ripper
My regular machine is in the hospital so I am using it to hold the acrylic "sew steady" table in my recessed desk for the older machine (I don't have one to fit in the desk for that machine) so that it doesn't slide around
