Time to update your design resource library! It's always good to keep it filled with all of the latest goods found around the web.
Yesterday I finally finished the layout for a project we're doing. I had to use a wood texture in the background, but finding one that was nice enough was quite difficult. Then after I had finished it, I began looking for textures at DeviantART, and that is the ultimate place for textures.
I found a whole set of these, truly useful and handy, going through polished wood to old, crooked and even "raw" wood. Some really beautiful textures. And the best is that all of this is for free. I hope you find useful my selection. Cheers! ;)
