I recently went to an OESD (embroidery) class at my favorite sewing machine store, I think the fee was around $39, it was a trunk show but suppose to be an update on all the latest techniques, threads, notions, etc. Ended up being the same old same old, spent most of my time out of class talking to the people in the store. Even the owner admitted he was very disappointed in the presentation, like me he thought it was going to be an update. I did learn a couple new things so all was not lost.
