I just finished this cover for my Bernina 830, and plan to make matching covers for the rest of my machines.
This was my prototype, designed completely by me, but there's a number of changes I'd make now that it's finished. But I like it well enough!
The fabric circles are appliqued on, I used some decorative stitching here and there, some embroidery, and a bit of lace and buttons.
