I am planning to use existing fence pickets to build a shed and use them for siding. But I can't figure out (or come to conclusion) on how to deal with the 4 corners. I highlighted red in below
That one looks like it's just a 2x4. So how can the fence pickets not end up to be ON TOP / OUTSIDE of the 2x4 framing?
I looked at this video online and they installed a corner board: https://youtu.be/Z00berTW5hc?t=43m8s
So I assume it's something like this "Outside Corner Moulding", right?
I am trying to save money and not buy additional corner board if possible. So how do I do this with existing 2x4 framing or fence pickets? That'd be great.
