Aha! So that's what the magnets are for. I'm sure it will be a piece of cake to figure out how to use that!:) No need to stack anything to use the tiles in photoshop; it will stack them automatically when you use them as a pattern. Just open the tile picture, do a select all (this puts a dotted line around the edge of the image). Then under 'edit' select 'define pattern.' This turns the tile into a pattern that you can use for painting. One way of using it is to select an area you want to fill with the pattern (I often use the entire surface of the texture image, for full coverage.) Then you go to edit, select 'fill', and in the dialog box for the fill process, select 'pattern.' Another way of using the pattern is to go to the tool box, select the pattern tool (it is the alternate for the rubber stamp tool), and you can paint the pattern in whereever you want it.
