How do I fix this horrible hex map?

Hi!

I'm just messing around with hex maps, but I am really horrible with "graphical things"

I've tried to have a background and to put on it an hexagon in order to use Rex's board plugin, but I don't undestand how to "fix" the map in such a way to have hexagons to "touch" each other.

I'm pretty sure is something pretty obvious, but I haven't found anything like this on the forum... maybe because it's too obvious ^^;;

No one?

Not even rexrainbow?

you probably need to reduce size of HexTx....

..but do not ask me why..

So empiric mode on, uh?

Many thanks, it worked, even if I would have understood why
