I'm trying to a Rey Za Burrel/Rau Le Crueset wallpaper. I'm thinking of something like a DNA strands background but I seem to have trouble with it. does anyone have any ideas how to make a nice DNA background using Adobe Photoshop?

Well, you can draw a vertical rectangle down your canvas. Go to filters > distort (? can't remember) > shear and choose your curve. Experiment a bit and if the curve isn't what you want, just hit Ctl+Z.

When the curve looks a bit like a sine curve rotated 90 degrees, and you're happy with it, duplicate the layer, go to Edit> transform> flip horizontally and there you go... move your dupe to overlap the first layer and you should have a funky DNA looking thing. Then you can rotate it, make it bigger or smaller and double click the layer to see the blending modes and other things. You can add a gradient... texture etc etc and it should look pretty cool.

Otherwise you might want to googly up some images of DNA and just extract them from there lol... but make sure you choose the Large Images only option.

Cool... thanx for d advice

Yea..it realy works ..so 10x
