Pinback - Sherman
First upload of Sims 3 CC (patterns do count as custom content, right?). I hope everything works fine, and nothing goes up in smoke if you put these in your game.

Four patterns, all located under the 'fabrics' category. The files 'yule tree' and 'antsy' both have four color channels, while 'severed hands' and 'jumpy creatures' have two channels each.

And the trees only look like they're painted on wood because I applied the pattern to a paneled wall covering in-game, merely for purposes of graphical representation. You may use them on clothes and fabrics, and they won't appear wooden I promise.
If anything doesn't work, let me know via comments.
