So that is where it went! ;-) I have or rather had one. It is used to place over the top of the pages in a hymnal or music book to keep the pages open when you are playing the organ or piano. Hard to explain, but kinda like a giant paper clip. The 2 center prongs go either behind or in front of the pages and binding of the book and the outer 2 go in the opposite position (behind or in front of the pages). If there is a quilting use for it, I am not aware, but am open for suggestions...if I could just remember where I put mine! ;-)
