1st time I ever traded in a machine was just a couple years ago. My Viking Designer1 did me well for 15 yrs and I'd purchased many feet, bobbins and hoops for it. She told me only the original parts did I need to bring with the machine. Luckily only 2 feet and 1 hoop would not work with the new Epic I traded her for. And it was just in time too as the screen went out on the D1 shortly after I traded her in. Lucky for me.
