I am a teacher, as well as a lecturer. My samples are hung in the shops with description along with my phone number incase they need clarification. I travel to teach at Quilt Shops and guilds. I try to make everyone comfortable, I applaud using stash fabric but always give them other options for adding to their palett at the QS,and they always want to buy more. I pride myself in being a good teacher- people travel to take classes from me because I am personable, helpful I take everyone from square one no matter how expert they claim to be and they always learn alot from me. People know what they get from me - my passion, my classes fill even in this economic turndown. I also make myself available to them on a certain date at the shop if they are stuck on something and need extra help (at no charge) So Sorry you had a bad experience. Keep trying, you will find a teacher you like and learn alot.
