I need a way to fix the line near the top of the picture. I'm trying to make a clean transition between the top and bottom of the image, but I don't know of a way to do that. The overall purpose of this is just to make a repeating image that goes on forever up and down that looks like this. To make this happen I made the top and bottom meet in a proper way, but in the process, this line appeared. If I can make this blend properly, my problem is fixed.
