I have a project that I've tested and went through:

A breadboard prototype
A through hole circuit board

And now I want to make a more compact circuit board before I move to the pcb.  So I'm wondering about how to use headers for this last prototype.

I will basically mount an lcd and a Nano.  To keep size small I thought of having the nano connect to the through hole board on one side and the lcd on the opposite side.  I'm planning on using headers on the board and then just slipping the nano and lcd pins I to have headers.

What would be the best way to connect pins from the header pins of the lcd (on one side) to the header pins of the nano (on opposite side)?

I am a bit confused, but why not Vias and traces?

The last thing you did is where you should start looking.

I didn't get the impression a custom PCB was being ordered, but instead a "island of holes" board was being used to wire it all up.

I'd go with longer legged parts, like you'd find on a shield, then connect everything up with wirewrap wire, feeding it thru the holes in your perfboard.

The OP has added an image since my post.

For prototyping, solder wire wrap wire between the pins.

Since you are trying to connect opposite sides, using LarryD's picture, strip one end of the wire long enough to go through the board next to the header and then connect over to the header pin. I typically use a pair of tweezers to wrap the wire tightly around the pin and squeeze it tight. Then solder both the hole where the wire came through and the pin connection at the same time.

Ok so the trick is that wrap wire.  I only have hook wire which is thick and harder to bend.

OK thanks
