You can find patterns online for your sewing machine, but the ones I've seen don't allow for the clear slide-on table that I like to keep on my machine. Plus I usually like to do my own thing.
I began by creating my own pattern. I roughly measured the height, width and depth of the machine and added a bit for seam allowances. I cut the blue fabric to the size and pinned it, WRONG sides together. This blue fabric looks great the "right" way and the "wrong" way, so I made use of both on the sides and edges.
I quilted the front and back with my walking foot with the guide in a diagonal pattern. It looks really great.
It sort of looks like a big covered toaster(!), but I am pleased with it. On the left hand side I had to add in some inverted pleats to account for the slide-on table(that I didn't realize was much wider than the machine...how did I miss that?!)
I learned a lot along the way. There are so many steps I didn't do in order that would have made it so much easier to stitch had I thought about them before I began stitching. I have a new-found respect for people who make patterns. It takes a lot of brain power and time.
