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.

I took a zoom class for my Dinner Plate Dahlia from BobKat Quilts, It was a great series of classes. Kathy is a wonderful instructor who is always there for you.  In addition to the interactive classes, the instructional videos online are so detailed and you can watch them over and over. I highly recommend her classes.
