Well, I suppose a few things that would be helpful:
1) What is a good first project?
2) What types of blades are better for one application or another?
3) What are limitations of a scroll saw?
4) What type of wood would you not cut on a scroll saw?
Just a few questions off the top of my head. I want to make a celtic cross out of wood, and a scroll saw seems like the best way to do it. But I have no clue!
