In all my classes, I will show you exactly what you need and why.  Each class gives a list of the supplies or materials which may be needed or recommended. Don’t fall into the trap of buying lots of equipment you don’t need or will never use.  It’s expensive.  In lots of my beginners classes, I supply all the equipment so that you can try out without having to buy anything.  I also try and curate exactly what you need to help you through this.
