I bought a used embroidery machine - my first, and am starting to find my way around. It's a Brother PE-150, and I'm feeling limited with the designs that came on the machine. I understand there is a Download Box available for it, that you can just download items from the internet and then copy to a disk, insert it and you can start embroidering all kinds of designs. What I'm wondering is if there is anything else I'll need. If anyone has one of these machines, are you happy with it and have you run into any issues downloading designs?
