Thank you all for your answers. I couldn't figure out how this could be done and I'm so glad you all agree and it's not just me. lol I do use them for ribbons and hemming knits as was mentioned. I used it for a stained glass quilt. That worked really well but it was a wall hanging. I used to make my kids those really wide leg jeans because we couldn't afford to buy them. I used them to top-stitch the side seam, just like real jeans.
