Thanks moirarae! I actually did try this image with spoonflower's mirror option, but I actually didn't like it as much. But, given everyone's suggestions here, I am going to try something similar and attempt to get a seamless repeat. I think I will play with the paper tube method that glimmericks mentioned. I would also love some suggestions for digital manipulation if anyone can recommend a program for a beginner like me who doesn't have the budget for photoshop. Is there something slightly more advanced than picmonkey or picasa that is free to access?
