Congratulations! I bought my sewing/embroidery machine on a spur of the moment too. And I have never been happier about a purchase. I may understand how to use a computer, but combining it with an embroidery machine was something else. Luckily my dealer gave me a few lessons, but they were mostly about the basic sewing machine. He taught me how to download to the machine but combining designs on the computer was all on me. Luckily I had a friend that also wanted to learn come over and we practiced and played and laughed our heads off. My DH would sit in another room laughing at what we were saying. Most of it was, "How did we do it? How do we get it to do it again?" We wrote notes and within a few days of out trials we got it down.
She bought her own machine - but we still compare notes on our programs. She has the Brother PE770 - I have the Viking Designer Topaz 20.
I hope you have as much fun with your embroidery as I do with mine.
