Be PREPARED!!! By you being prepared, your students will also be prepared. If there are patterns and templates that will be used for the class, make sure they are available before the class. If the students need a certain book for the class, make sure they know that ahead of time and can have it purchased before the class (or make sure the LQS has the books available for sale). If specific fabrics are needed, make sure the students know this also. Have adequate space for the number of students, including outlets to plug in the machines. Have more than 1 iron available for a class of 15 or instruct students to bring their own. Be willing to get up off your chair and walk around and check on the progress of the students (I am drawing off of the experience I had with the one and only quilt class I took from my dealer) NEVER AGAIN!!! (They don't get my fabric money either)
