Hello everyone! I am brand new at this computer thing. I am a 64 great-grandma. 7 children,13 grandchildren and two precious great granddaughters! I have been sewing and quilting forever!!!!! I purchased my first Husqvarna in 1977. It was the first computerized machine they built. I am still using it today however last fall I purchased a new Designer I and I love it. I am not familiar with the 830 or 850 but I have never had a single problem with either of my machines. I want to start machine quilting (I am stilll doing it the old fashion way-by hand. I am somewhat leary of trying it on my own. Any good advice would be appreciated Thanks Sue
