I had an even cheaper, simpler, and cheesier method: Poke holes in grey cardboard (from shirts, cereal boxes, etc). Insert components on top surface, bend leads and daisy-chain as needed to make connections. You could even draw out the layout ahead of time on the cardboard.

30 years ago, when I was at Ginzton Lab, we had a couple of engineers who would build circuits for folks. They used a very similar method except with large paper stickers glued to thin balsa wood, and scribbled the layout on top in pen. You could just stick DIPs straight through it. They used copper tape a lot for ground integrity.

I did one with parts soldered to staples in grey card this was using recovered through-hole parts so the leads were too short to daisy-chain them, the solder and the staples were new, the rest was all recovered. it wasn't anything particlarly ambitious, just an LED blinker.
