This is my third jacket. It was heavy denim with embroidery. It wasnt that challenging, even though very thick. I have industrial machine that helped very much. Button boles were the biggest challenge! I had to do them manually on the machine. I love this jacket in the heavier material! I will get more pictures up soon! What advice would you give someone starting this project? Don't hesitate, just do it. The class will teach you many valuable things that you will use over again. Well worth the money.
