Unsure. It just says elastic thread .5mm. link to thread Looks like other people have had success, even the other brother users. I don't really think it being too big is an issue. From many a blog, video, posts here, .5mm seem the standard width. Im thinking this might be a newbie user to entry level/not amazing sewing machine issue. Thank you though for your input.
