I have done a few, but I never cut off the ribbing. I use the serger with same color thread or contrasting depending on look you want . Stretch the ribbing a bit as you serge and it will then ripple when finished. Looks really good. I have then either embroidered on them or use hotfix jewels to decorate. Make really great jackets for when you need a little something but not really a jacket. Good luck and enjoy
