For a minute there I thought you were going to say you picked them off
of discarded electronics.

I don't mind destroying a few 29p LEDs by accident, but I'd really
rather not die a virgin...

This is why you buy solid wire and not stranded! Though I have learned
that stranded is the best choice for hooking up external peripherals to
your circuit, when used in a project.
For extra fun, do something like this:

I learned a pretty important lesson with this project:
Put the jumpers on the component side, and use stranded wire for the
external parts (jacks, pot, power and LED) the solid wire made install
into the enclosure a royal pain.

Trouble is, you just can't *bend* the stuff! It's like trying so connect
components together with a coat hanger...
(Although, I bought 4 chunks of wire, and one of them actually *is*
single-core wire. While it's rather rigid, it's not quite as bad as the
other stuff.)

And 10 m of wire weighs, what, about 10 grams?
Oddly, both the single-strand and multi-strand cables appear to contain
some kind of white metal, not copper.

pff.. I did that, was highly dissatisfied with the result, and the thing
ran on batteries, which was inconvenient. So, I built one to my own
requirements. :D

Lordy, no. Nothing but the best for the maintenance department. :-)

You're not supposed to run breadboard wires around corners. You're supposed
to plug it into a hole and run a connected wire at an angle if you need angles.

See how the black cable goes from C1 to C2?
Or how the purple cable goes "around the corner"?
