I sure am glad to see that I am not nuts- my collection is small compared to all of yours. I think I still have a Moorse, an adler, Singer old straight stitch, a tredle a euro pro and one I found at a yard sale Singer 301A.
I feel like I have outgrown the quilt room and seem to have a problem of some sort with every single one of them. I have been researching new machines or used. OH MY GOSH unbelievable.
