Hey Thrifty Nation! I’m going to show you how to solder gpio pins to your raspberry pi with a breadboard! and to prove that this method works well, Instead of using a 2x20 pin header I will use two single strips and have them turn out straight I started by inserting the two strips next to each other in a breadboard, you will want them slightly raised like this to account for the hdmi connector on the raspberry pi zero then start by soldering the 4 corner pins to tack it in place, then proceed to go down the line.
This is kind of boring so I will cut ahead to the finished product.
