I am currently taking classes from a guy who owns a private leather store and he offers once a week, two hours a night, classes for 6 months at the beginner level (he starts with 12 and said his attrition rate is about 50% by the end of 6 months). Class #1 was casing and the swivel knife, then into other tools, etc. it will ultimatly cover sewing, dyeing, attaching hardware etc. I am not a beginner to leatherwork, but i'm fairly new to tooling. I figured even at that, I am hoping to break some bad habits. I am sure he will cover a lot I already know, but much I don't as well. He doesn't let anyone start at intermediate, you have to go through beginner. Then he only chooses 6 of the 12 to move onto intermdiate, as he offers more one on one time in that class. That one is once a week for a year. Hope some of this info helps, if you have any questions about my classes, I'll try to answer them By the way, he only charges $20 a month.
