Make a Custom Seasonal Background for Blogspot/Blogger Blogs using PhotoShop

Literally HALF OF THE STAFF at CraftyGirlSquared and the ENTIRE STAFF at JuBee's Craft Box have been asking me to make a tutorial of how one can make a holiday themed background using Adobe PhotoShop.

I don't know how many of her, er um, I mean their fans, are using PS, but here it goes anyway.

By the way, I'm using Adobe PhotoShop Creative Studio 4 64-bit Edition, so your results may vary if you're on a different version.
