I'm considering investing in an embroidering machine and wanted to get a few things cleared up. Basically, I'd like to create designs in Photoshop, import them into Embird, then download them into the machine. I'm very confused about what machines will do this. Listings seem to make a lot of assumptions. What feature should a machine have to download from a computer? Just a USB connection or does it need a floppy drive? Some machines like Brother and Singer appear to have proprietary software...is that because it's only used to make some kind of card? Do you burn a card like a CD and pop it into your machine? Any guidance would be greatly appreciated.
