You can turn any background paper into a pattern.
How cool is that?
Open a 12 x 12 paper from a kit
Then Image/Image size, change it to 3 inches x 3 inches.
Then go to Edit/Define Pattern
It is now stored in your patterns at the bottom of the stack.
So when you go looking for it, scroll to the bottom and there it is.
Let me know if this works for you.
REMEMBER DO NOT TO SAVE THE FILE AFTER YOU RESIZED IT. If you do, you'll need to find the original zip file and extract it again to get the full size paper back.
FYI, you can vary the size and resolution to make the pattern but beware that you don't want it too big.
Also patterns created in this way are limited in their use.
Open a new document add a new layer and fill it with any color
Click on the FX Pattern overlay
And fill the entire area with the pattern.
You will see all kinds of funky edges.
There is a way to solve the problem, but not with the easy pattern method I just mentioned above.
This easy method however, is just wonderful for small areas.
And you can adjust the size slider to get rid of some funky stuff too.
