Have you used their varigated thread? doe you have any issues with varigated or the cotton thread from Glide? I can not get king tut varigated to run successfully in my millie and it is really frustrating.
Not yet for the variegated but as I need a certain color I will be purchasing. I've never liked cotton threads, but that's me. I do use cotton wrapped thread for piecing but not for quilting. In my quilts from the 50-70s which my grandmother quilted by hand They really should be redone as the threads have started to break down. It's really what you like its not what some else says. There aren't any thread police. I like how the quilting looks with Glide, Lava and Perma-cord but have used Signature, serger threads, tiny spools of dress making threads. Depending on what I had in the cupboard and if the color was the one I wanted.
