In addition to the resources & techniques already mentioned, here
are a some ways to make patterns "seamless."

The quick & dirty method to make an image or doodle into a seamless
tile is with the command at Filters > Map > Make Seamless.  If the
image content you are making into a pattern is random or
blurry-looking, this method can give very satisfactory results.

A "better" tool for automagically making an image layer tileable
lives at Filters > Map > Resynthesize.  Tick the check boxes to make
the output vertically and horizontally tileable, run the filter, and
voila:  The layer is rebuilt as a seamless tile that very greatly
resembles the original layer.

(I freaking LOVE the resynthesizer.  It is also available via
Filters > Enhance > Heal Selection and Filters > Enhance > Heal
Transparency.)

The precise, completely manual way to make an image or doodle
seamless is to use the command Layer > Transform > Offset > Offest
by x/2, y2.  This command scrolls the layer 50% vertically and
horizontally.

Manually fix the visible "seam" that appears across the horizontal
and vertical center of the transformed layer, and it becomes a
seamless tile.  The Clone, Heal, and Smudge tools are potentially
useful here, as is the iWarp gadget in the Filters > Distorts menu.
 The Heal Selection filter mentioned above may also come in handy.
As long as you do not change the edges of the transformed layer, it
will remain seamless.

In all of the above cases, you can test your result by repeating the
Offset by x/2, y/2 command.
