I have 5. 3 of them are embroidery machines, one is for taking to quilt guild when we have a class, one I took to my daughters, because she always either brings me stuff to alter or mend when I go see her or she comes to see me, then I have to mail it back to her. She lives in Ogdensburg, NY, I live in Tennessee.
I also have 2 sergers (one is at my daughters) and a professional hemming machine.
How many can I use at one time? 2
I am looking for an antique machine, that I can afford. LOL
