I did some designs and then went back over the top with it over and over to build up almost a solid disc. The overlapping lines on the last one are so thick that it almost looks like a vinyl. When you compare it with the one that has one layer of line, they both look very different from one another.
I think the middle one looks most successful. The lines look almost undistinguishable in the last one so I think maybe it's better not to make it too dense.
