Sounds like me last night. Needed to make a pair of pillow cases for a wedding gift for today. A friend came over to sew too but she is less experienced than I am and I am pretty rusty. After helping DF (dear friend) who was cut happy. I finally started on my project. Had to change the serger thread. An hour later, the ding dang serger would not sew correctly. Move on to the Bernina 730. Part way through pillow case one the bobbin case fell apart. Move on to the Janome...that one was a bit wonky too. Almost had to go to the ancient Viking but I finally got both of them done.
