Due to popular demand, not really but one person did suggest it, I scanned some toilet paper.
It ended up working out really well as the surface pattern happened to line up with the square crop so I didn't have to do much touching up for it to tile. The final product consists of 2 scans, the papers surface and the end of the roll.
One last thing I could have done was to punch in the holes of the tube so they are not just black circles, maybe next time.
If you want to see how I'm doing these scans head over to my blog.
