Two good wire joining wrap techniques I found on Tumblr. One's the red set, one's the blue set, sorry they're interleaved it was a gif. But they're definitely going into my how-to-wrap-wire brain toolkit.

@moira @Binder These are cool. My fave connector is that new shrink tube that has a ring of solder in the middle. You slip it on one wire, twist your other wire any way you want, slide the tube to the middle, and hit it with a heat gun. Ugly but super rugged.
@scenario @Binder Oh yeah, I saw those somewhere like six months ago and have been using them where applicable a lot since. ^_^
