I have a Janome 350e embroidery machine & I would like to use it for embroidered quilt blocks. My problem is that many of the websites do not sell in the "jef" format. I have heard that this format is no longer popular and I should order the "pes" format. Has anyone tried that on the Janome 350e?

I normally download designs to a usb, but I'm afraid to try the different format. Would appreciate hearing from anyone who has the Janome 350e & used the pes format instead of jef.

Thanks for your help.
