I made some no-frills covers for a few of my antique machines which had no covers. I also have a Q-16 and looked for a pattern for making a cover for it. There is one for purchase by a Bernina representative, but it's crazy expensive. I have just been throwing a sample quilting piece over it, but I, too, want to make a cover for it. I think I may use a pattern for a sewing machine cover and just adapt the measurements to the long arm. If you make one, I hope you'll share what you did here!
