hi Cere,
you're correct that you can cut that type of LED tape along any of the
dotted
lines. It's made up of a bunch of independant circuits which each have 3
LEDs
and resistors and run on 12V, and then they're all in parallel for 12V
down the
whole strip. The current draw from your 12V power supply will change with
the
number of LEDs, but the voltage will always be 12V.

I’m sort of an LED nube and am looking for confirmation that this:

works they way I think it does. My only question, really, is whether I
can
just cut the strip at the designated locations and it will work fine with
a
12v power supply without any need for extra resistors? It looks like the
LEDs all sit in parallel along the strip so therefore…?
Thanks,
Cere
