I have ween them in Pattern books I believe. But there so many different sizes of Machines these days I think it might be best to make your own. Sara

Monica, I beleive you can make your own - fairly easily - take measurements - as you need to know them. *4U

These are not specifically for your machine, but maybe you could adapt one to fit.

I suppose you have to design your own, because there are so many different models.

I just turned my fabric inside out and pinned, snipped, then sewed. I made the machine portion and the embroidery arm cover separately, then attached them together. Nothing fancy but effective in a fabric that is easy to slide on and off. Took all of about 5 minutes. Blessings!
