I found it! I found it!!
A few weeks ago, on one of the threads, someone mentioned a wavy line stitch. I was amazed by this (don't judge me and my ignorance). I was convinced that my mom's machine didn't have such a thing. Well, lo' and behold!! I found it today!! I love it!! I was making a larger receiving blanket for my grandbaby. She loves the one a friend of mine made for her but she's outgrowing it already. And I needed a decorative stitch to put around the edge so I was playing around with the wheels and there it was!! I just had to share!!
