I also learned that it is unwise to try and fix my machine by taking it apart when I should be asleep in bed. There were some sweary words not befitting a respectable sewing mama! Plus, I would probably not have had to take it apart in an emergency situation had I not left the dust cover off for days at a time. Lesson learned!
And finally, I've learned that something lovely can be made out of leftovers - I didn't buy any new fabric for my learner quilt. I was inspired by a quotation that I saw in a small town sewing shop in New England whose name I don't recall:
If life hands you scraps, make quilts!
