I really like your hybrid teaching concept with great in-person instruction, supplemented with videos shared before and available for review after the retreat.  I think that is more of the way the future will look.  Many traditional quilters like the in-person sessions, and I understand that. But those of us with jobs and kids and other responsibilities cannot afford to be away for long periods of time.  While this was a table topper class,  I did purchase a queen size pattern, so it was worth going thru the class versus doing something from videos only.

The Fundamentals of Quilting was a wonderful class, lots of information and links to fully understand new techniques. I finished the class with three sample quilts and ready to tackle bigger projects. Kathy has a wealth of experience and willingly shares, answered questions and helped everyone be successful. Most classes went over in time.  Make sure you budget time to practice between sessions — She’ll give you instant feedback!
I would definitely take another course through zoom, as I still have so much to learn.
