Below is a link to a Youtube series that Wray has been working on. I have been following this Jag bonnet shaping series and, as always, Wray delivers. If I had had access to this detailed training 30 years ago there is no doubt in my mind that I could have shaved about 5 years off my learning curve. (Im a slow learner)
The information will benefit all levels but for you new guys, this should be viewed and studied until it is burned into your memory. When I was starting out, I didn't understand arrangement, shaping, and area value. I would have given anything for this information. Wray covers all this in depth along with flexible shape patterns. Wray also holds training classes at his shop. If you can, I would suggest attending. I think he would be pleasantly surprised if you walked in the door and already had this knowledge.
At the moment there are 4 parts and he will probably wrap it up soon in part 5.
