I just found two really cool sites that let you make tartan plaids and stripes from any color combination you choose! Or, you can find one that someone else has made, and save that. They are perfect for using with Photoshop to create patterns. The sites are set up the same, so once you figure one of them out, you've learned the other one, too.
Tartan Designer - Tartan Maker - Tartan Background pattern generator
Stripe Generator - ajax diagonal stripes background designer
Check this one out that I found for Christmas:
Christmas Plaid That Corky Made
TIPS: If you see a plaid or a stripe that you really like, take note of the settings that the creator used so you can duplicate.
Also, if you have any digi paper you want to match, open it up and copy the color code and paste it into the Tartan or Stripe generator.
I'm into making my own digi designer papers, and this is a huge help! I love Christmas plaids!
