You don't suppose this has anything to do with the aging process?? Nah, couldn't be. I had a ruler/template for circles, the one where you lay it on the fold and cut or make with a pencil the size circle you need. I can't find it anywhere, been missing a couple of years and I am determined not to buy another one! I also am missing my spindle that fits on sewing machine for the spools of thread that have the large hole, that one I think fell into my wastebasket!
