I personally use PE-Design 7 software when embroidering with my Brother SE400. All my PES files can be used with PE Design as well as many other embroidery softwares out there. If you need something converted for a specific machine such has a Viking or Singer use the contact page to request it and I will put it up on the site. Also if you have a special request I will take them through the contact page as well. I hope that this site can be helpful to all the crafters out there by saving you time and money.
