If you haven't found Exnovodesign, check it out. It is hosted by Amanda Whitlatch who is a Bernina Educator.
There are videos for the Bernina 830. I have watched several of them many times and I pick up a new technique or tip each time.
Projects are listed and added monthly. It is a good source for inspirational ideas. I just saw a couple of things that I need to look at further. There is a new instructional guide for mitered corners with the binder. That is a problem that I have had in the past with the binder.
She has a technology blog. I highly recommend Ccleaner that she mentions in the May post. We use it at work and I use it at home. I have never heard of the other program but I am going to check it out.
There is a lot of information and many videos for the embroidery software. I have learned many things by watching the videos.
Be sure to explore and see what you can find!
