Lots of good advice.
Learning from a tyer that has been doing it for awhile is very helpful.
Just my opinion but you don't need to spend a zillion dollars on super expensive equipment to get started.
A good solid vice, some basic tying tools, thread and some materials are a great start.
There are also tons of very good youtube videos available online.
An excellent resource for patterns and tying techniques.
I took out a number of library books when starting out that helped as well.
Don't expect to save a ton of money from this venture.
Have fun!
