All it took was another rethreading and some TLC. Yep, my serger's all better now, at least for the time being. Good thing since my sewing machine won't make button holes anymore. I was planning on a shirt, but went with a dress instead. I just finished up the hem...and the dress is SO cute! I'll share photos of the finished item when it's a little nicer out, and not this icky snowstorm.
