thanks for the suggestions guys i really appreciate the feedback, it just so turns out i actually am looking for a way to shade the edges and make it look like the remaining pieces of map are wrapped around some kind of dowel. Being new to not only mapping but also to using Photoshop (and doing anything that is really considered "art") it's a long road a searching for, watching, and failing at tutorials until i finally get things right. So once again any and all help is appreciated.
Also if anyone has any suggestions on how to place large river that takes up a decent part of the main landmass and facilitates trade i'm all ears.
Thanks Again
