How do I write a solid plus sign, like the American Red Cross symbol/logo?
I'm a novice, so I'm not very good at going to CTAN archive and downloading and installing business — it doesn't work half the time. So it would be nice if it doesn't involve too exotic packages.
Edit : I would like to use it in math mode.

If you just want a fat plus sign, which need not be identical to the American Red Cross logo, a pure Unicode (LuaLaTeX) solution is possible. You just need a font that contains either the ✚ symbol (U+271A Heavy Greek Cross) or, perhaps preferably, the ➕ symbol (U+2795 Heavy Plus Sign).
Here’s an example using the (too?) heavy greek cross symbol from the free font DejaVu Sans:
This has the advantage that you can copy and paste the text from the resulting PDF document without losing the cross symbol.
