Great visual! Thank you for sharing
I've now 'Subscribed" to The Quilt Show on YouTube!
I believe I also learned about Bernie's book
You and Your Sewing Machine: A Sewist's Guide to Troubleshooting, Maintenance, Tips & Techniques from a previous post on the QB and purchased it about a year ago. I immediately read it from cover to cover and found it equally helpful and have referenced it a few times since.
