I don't like invisible thread because it seems more like fishing line than thread. I know a lot of quilters use it, but for myself, I like to see the quilting stitches. It makes it seem more, I don't know, old fashioned. But then, I like old stuff, even if it is modern made. Heck, I do all my quilting by machine. I just like the look of the quilting thread stitches being visible.
