Hello boo6204,
I also can't find the particular blog you mentioned, but maybe I can help anyhow (if you still need it at this point). For those of you who don't know what a Photoshop Style is, it is a particular range of settings that are used on a single layer to change that layers appearance. Whatever is done on this layer, whether it is brush strokes, fills or text will take on the effects set within the layers style. So. How would make one that uses ArtRage Glitter (as a backdrop I'm assuming) was the original question. Here's what you do:
1 - Create a new document in ArtRage 2.5 (it has to be the full version or the glitter tool will be locked). Make the document about 500 x 500 pixels.
2 - Choose the color (or colors) you want your glitter to be and completely fill in the entire page with glitter. It should look something like the image below:

3 - Export the image as a PNG file (I called it glitter, so the file would be glitter.png).
4 - Open Photoshop and then open the glitter.png within Photoshop.
5 - Select Filter (at the top of Photoshops window) and highlight Other and then select the Offset option (see image below).

6 - After playing with the Offset options, you should end up with an image that has two straight line going through it. It may be difficult to see in my image, so I put arrowed lines showing the location below.

The reason we do the Offset is so we can eliminate these lines and make a perfectly tiled image. So, on to step...
7 - Select the Clone Stamp tool. Be sure it's not the Pattern Stamp tool, by left clicking and holding down the button to bring up the floating menu with the two stamps listed (See image below).
