Every time I try making a tileset, I end up with things like this:

On the offchance you don't think that looks bad, look what happens when you tile them:

What the fuck am I doing wrong? It looks like a fricking thermal image!
Tiled images should be very simple. You notice that from RMXP's graphics. All tiles intended for tiling have a very simple texture, usually just some colored noise like the grass or the sand.
Yeah, what Blizz said. Best thing you could do is start by making lines that go straight across the pattern (Diagonally, Straight, In a wave pattern, whatever, as long as it ends up starting where it finished on the other side). Or, if your Fill tool supports it, switch from Fill All (Or whatever it says in whatever program you're using) to something like "Lines" or whatever. Then it'll make all those lines for you.
This might be a bit complicated, maybe picture tutorials would help.
Back to experimenting it is then. Thanks for the pointers, guys.
