Congradulations on your new machines. If I may, I suggest that you go to
www.cuteembroidery.com and sign up. It is a forum much like this one but mostly directed to machine embroidery. You will find very knowledgable people who will answer your questions and give you help on starting out. Also, many of them digitize and offer free(look under Designs By Cuties) their amazing designs. Have fun!
