Rippled Sand Background
I have always enjoyed taking images of textures. I also enjoy taking everyday objects and capturing them usually as a macro so that they become abstract and out of the ordinary.
Rock textures are one of my favorite things, and I have found that web designers like to use them as backgrounds for web pages and for banners.
I do not know if blogger allows us to design our own themes - I have used the CSS to change some of the colors and settings, but have not tried anything beyond that.
I know that wordpress is very customizable and you can even develop your own wordpress themes.
I was looking over some of the ones that can be used and I found one with a gradient background that I wish I could figure out how to do with mine.
Still giving some thought to getting my own domain and website for my blog and am still on the fence regarding it. Having customizable themes is certainly something to think about.
