my advice for a bigger saderan is to bump up all of the values from the tutorials. It works for most of them, but a few get weird since the values max out, especially in the layer styles. It's still possible though. You might have to create some effects by hand instead of the layer styles if you want to go really big.

I did this using saderan's tut but also incorporated some stuff from one of the wilbur tutorials. It's 8in x 6in at 300dpi. it still needs some tweaks as far as the scaling of the patterns, etc. but overall it only took some minor adjustments to the tutorial to make it work. The nice thing about layer styles and adjustment layers is you can keep going back and changing values until you get something you like.
