Think back to the last time that you attended a 4 day workshop where you packed and traveled to a destination, unpacked, checked into the hotel and then shared the teacher with 14 other students.
The teacher might give a lecture, then split her time between 15 students. This continued over the next few days. On the last day, most of the time was spent settling bills and final questions.
So, how much time did you actually get with that teacher? How much did you learn?
How fast did you hook? Did you get answers to all the questions on your rug? Do you even know where the trouble spots are? Four days is not enough.
What happens when you get home and you have more questions? FYI- I encourage my in-person workshop students to join The Rug Hooking Journey Membership and ask questions during Office Hours, which happens every week. Most teachers do not offer followup.
