I have them for my Melco EP-4 which is identical to the Janome MB4. I love it for difficult items, like pockets, baby shirts and onesies, sleeves, trouser legs etc. It's ideal for all those items that benefit from the free-arm. But for the normal projects I prefer the sturdy hoops that came with the machine.
Thank you so much for your comments. I have some sewn projects that I was hoping to embroider so I will go ahead and buy them. hugs Helen
Sorry Helen - can't help with this question. I only have a home embroidery sewing machine - Husqvarna Designer 1. Love Chris
Chris. These look so much easier to use for embroidering especially socks, gloves bags sleeves etc. hugs Helen
