I have a basic Brother SE -350. I download free ( or purchsed) emb designs from the internet to my computer ( they usually come as a ZIP file). After downloading , I then extract the file. When I am ready to use a design, I use PED-BASIC to upload the design to my memory card. The SE-350 does not have a usb connection. I then insert the card into my Brother SE -350 and I"m ready to embroider.
