I admit, I measured to make my machine covers. I didn't want to pay for a pattern. I know of no pattern so I can't help you there. If you Google sewing machine covers you will probably find a lot of ideas and maybe even patterns for them. I hope you do find what you want.

I have recently made covers for both my daughter's machines. I just used the original covers as patterns but I am sure it is easy to cut a pattern just by drawing an outline of your machine. $15.00 seems quite a lot to pay.

I simple measured my dimensions and constructed one from those it really isn't that hard to do. It also covers the embroidery arm since it is attached most of the time. Great time saver for me.

I usually make my own too.. Give it a try... It is eaier than you think!! Suzanne

I just made one up for mine by using the measurements of my machine. If you aren't used to constructing patterns, make one from muslin or a scrap that you have first to get comfortable making it.

I went to youtube.com and typed in sewing machine covers. There were a few different one's there that would tell and show you how to measure your machine and how to put it together(free). I've made 2 of them and I'm going to work on my third one soon. They were really easy.
Good luck

Are you familiar with annsultfixit site? She offers a free d/l of her pattern to fit her Brother ULT. You need to transfer to 1" grids. Well, I have 2 ULT's and I have done the transfer and made 2 covers for my machines. I just visited the site and found she has revised the pattern, so I do not know how this one fits my machines--but you could do a bit of alteration if needed. I'm adding an image of one of mine (I recovered the chair to match). I added the lift straps ar the back and over the 'arm. I love the way mine fit,...and with the arm removed and the sewing/quilting table attached, it also fits that! It is a free d/l..read what she says at

Thanks I plan to give this a try.
