What other embroidery cards can I buy for my envision 9008?

You can download designs from the Internet and send them to the embroidery machine.

If this machine uses memory cards, you will need a reader/writer unit and a rewritable memory card in the format of the machine.

If the machine uses floppy discs, you need a PC that has a disc drive for floppies or you will need an external drive.

Check the Internet for vendors or check with the shop where you purchased the machine for the method of transfer needed.
