You can start out really cheaply in the beginning.
Straight edge, razor knife, awl, contact cement, sand paper, wing divider, neeedles, thread, wood or bone slicker, edge beveler, dye, and some edge finishing component (gum trag, wax, or even spit).
Most of these tools you probably already have lying around the house.
Do a few small projects and see what tools you need next. I didn't add carving tools to the list because you can make durable long lasting products without them.
Good luck and have fun.
