A recent poster asked about machine covers. Due to different machine sizes it is difficult to recommend a specific pattern. It is easy to make your own pattern.
Simply measure your machine. Add one inch for seam allowance so you have a little extra room. You can fit the pattern to muslin first and pin or baste together. Re-use the muslin pieces later as desired.
Try the cover on the machine for fit. Hemming is done last. If your machine came with a plastic type cover you can use it for a pattern too.
A few How-To in case you are interested and need more directions.
