First, Take a deep breath, stop obsessing, don't worry about the bag you use to take things to class, dress comfortably, use old dependable machine but above all enjoy meeting new quilting friends, enjoy learning a new techique and maybe find a new techinque you just love and were afraid to try before being brave enough to take a class. Don't forget to give yourself a big pat on the back for being courageous enough to try. :-D :-D :-D
