my Nolting Quilting Bee (sitdown longarm) uses class “M” bobbins. I recently ordered pre-wound Magna-Glide class “M” bobbins, but due to a backorder of a specific color i received that color in a class “L” bobbin instead. While you obviously cant use a class “M” bobbin in a class “L” situation - is it possible to use the smaller class “L” bobbin in a machine set up for a class “M” machine??? If i sound totally confused - youre right because i am!

Thank you for any light you can shed on this subject!
