Help making swirls & wavy lines
I have seen many designs that include swirls and/or wavy lines. Anyone able to post how to make them? I have attached an design example with the wavy lines.

Look into Filters/Distorts, in particular the "Whirl and Pinch" and "Waves" ones.

RE: Help making swirls & wavy lines
I just downloaded a script directly from GIMP's Plugin registry that allows you to draw geometric shape paths. Amongst these shapes are rectangles, triangles, 3 different types of waves, and more. There are rectangle waves, triangle waves, and sin waves. I tried the "Whirl and Punch" and "Wave" approach, but didn't quite get the result that either of us were looking for (I also need to draw some wavy designs for a brochure). Anyway, here is the link to the script.

http://registry.gimp.org/node/59

Once you download it and put it in your scripts folder, follow the images for instructions:
Begin by clicking the "Script Fu" tab which should appear after you install the plugin.

Adjust all of the preferences and make sure the "Stroke Path" box is checked, otherwise it will draw nothing.

The wave, in this case, will look like this:

RE: Help making swirls & wavy lines
Paths are also a solution.... but in this case it's even better to do it by hand. Making a wavy line with paths isn't difficult.

And, if the suggestion to use the shape-paths filter above is good for "regular" shapes, I don't recommend to use its "Stroke path" because this means you can't tweak the path obtained and you are limited to fixed-width curves. A better usage is to use it to generate multiple path "strokes", then connect them using the Path editor tool to make a closed path, and make a selection from that path and fill it (bucket-fill or else). For instance:

1) use shape path to produce two sine paths (don't stroke them). Make your paths wider
than the canvas (yes, you can...). Note that if you produce two identical paths, their display sort of cancel each other (XOR display).

2) Use the Move and Shear tools in "Path" mode to shift and distort them a bit

3) In the Path dialog, merge them (Merge visible paths)
4) Use the Path editor to connect their ends and make a closed path:

5) Path to selection, and fill with whatever (here a red/yellow gradient):
