ELEMENT: Rick Rack and Easy Plaid
ScrapbookBytes website has some great tips on how to use Photoshop to make digital elements for your pages.
For example - check out their tutorial on how to use Photoshop to make RickRack.
Also worth a look is how to create plaid paper from striped paper.
What I like most about the site (from a scrapbooking perspective), is that the tips and techniques are relevant to scrapbooking itself, not just vanilla image manipulation.
