Well, I have good news and bad news.
The good news is that I quilted for about 25 minutes yesterday. I did complete the purple braid quilting. I also started to finish the orange braid quilting, but the bobbin ran out and the bobbin winder is 2 floors below this machine. I did not sew on the black or red braids, nor did I unpick anything.
Tonight I have one test. The goal would be to finish the orange braid, sew 10 on black and red and unpick the brown braid. Slowly but surely, I will get there.
