Bow Design Questions

Hi all. Still very new to traditional archery, and incredibly fascinated by the idea of making my own. To that end, I have questions.

I bought a 1x3 oak board for my first attempt. My main question is...should I try a flat bow first? I have heard that they can be a bit more forgiving, and I want to give myself the best chance of success.

Also, if I do go with a flat bow design, will there be a need for an arrow shelf? (I'm basing more off of an ASL design, but with wider limbs).

Any advice is welcome. Thank you.
