Hello, Leslie:

Making seamless tiles is a bit of an art in itself but there
are two basic ways that I know of.  With both ways, you
will need some sort of image manipulation program, such as
Photoshop (recommended) or the equivalent.

The first method is to:
1. Make a note of the size of your image.  Let's say, for example it
is 100x100 pixels.
2. Select the entire image and copy it into the clipboard.
3.  Create a new file that is exactly double the height and width
of the original image.  For example, 200x200 pixels.
4.  Paste the image into this file and move it up into the upper
left-hand corner.
5.  Create another layer (if possible) and paste the image a second
time into this new file.
6.  Move the second pasted image into the upper right-hand corner
and flip the image horizontally.
7.  Again, create a third layer and paste the image a third time into
the new file.
8.  Move it to the lower left had corner and flip it vertically.
9.  Create a fourth, and last, layer and past the image into it; move it
to the lower right hand corner and flip it vertically and horizontally.

If you've done this right, you should have a seamless tile--at least as far
as the edges and corners are concerned.  However, you may notice
that it still doesn't quite look right in the middle, where the four pasted
images come together.  At this point:

1.  Flatten the layers, if you're using Photoshop, or save it as a TIFF or
targa--whatever file type you use--if using another program.
2.  Using your program's version of the stamp tool, stamp the center
seems the best you can.

This should do it, but, as you can tell, it is the long way.
However, if you are using Photoshop, there is an easier way:

1.  Select the image.
2.  Select Filter>Other>Offset.
3.  Type in numbers that are roughly half the image's size.  This offsets
the image and creates perfectly tileable images, as far as the edges are
concerned.
4.  Use the rubber stamp tool in the middle as I already outlined.

Making tileable images is a bit of an art, but with a little bit of
practice,
it is really quite easy.  Good luck.
