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.

Five Stars for Fundamentals of Quiltmaking!
Kathy provided a clear outline for each week. We were provided with instructions on cutting out fabric to prepare samples of the blocks and techniques that were going to be demonstrated in the upcoming that class.  We were also were encouraged to message any problems we were having or questions. Her responses were always timely and offered suggestions. We all proudly displayed our finished blocks for that session. We also were provided with additional resources.
I have been quilting for a few years but still referred to myself as a beginner.   After this class I can walk through that door!
I can now do partial seams, flying geese, prairie points, a true 1/4 inch seam, and curves. Plus so much more.
I highly recommend this class.

If you are even thinking about this, (commenting on the Quiltworx Star Course) I can assure you that Kathy is the instructor to help you make a beautiful keepsake quilt. She helped me tackle the Dinner Plate Dahlia.  She is the best!
