I haven't decided yet which is worse, the carpet monster or the "hardwood crunch". I even tried gluing all the parts together to keep them from getting lost,,,,,,,,you guessed it, before I got them all in one clump, one of them bounced off the hardwood floor and got lost in the carpet in the next room. (please respect TankerBuilder's feelings, I am sure discovering fire with his flint tools on his tenth model was very traumatic)
As for the classes asked about in the original post,,,,,there is a "sort of" class at some model shows,,,,,,it is called the Make And Take program. If done by people that really want to help out, there is more than just a "free kit given to the kids to build", the leader of the M T group gives lots of feedback to the kids, and is there to answer any questions.
One thing that helps a lot with new builders are those paperback books for beginners,,,,,Kalmbach sells them, as does Evergreen. Once you learn about cutting parts off instead of breaking them off, glueing, filling with putty, sanding, painting, things like that,,,,,,,,,each of us does almost everything differently. There are two or more choices for methods and products for each step of the way, it is rare to have two people do everything the same.
