I just received my PE770 and am anxious to get started using it. Just wanted to know what software do you use if any or is it really necesary in the beginning. I understand there are designs on the machine I plan to practice with, and I also understand there are plenty of free designs I can download on the usb stick to stitch also. But is the software mainly for resizing or what else may it be used for, if you can enlighten me. I would appreciate your comments as a newbee.
