There are hundreds of free designs to be had on the web but you need to know what kind your machine takes.
take as much time as you need to have him teach you simple file transfer from PC to sewing machine...its worth thousands of dollars in designs down the road. You will be able to search out and find your own free designs.
One thing to know..some of the free designs are made by novice digitizers so before commiting to fabric its nice sometimes to test stitch a design out....you'll learn : ) Congrats!
