The drawback is that, unlike Woodstock's creation, there are no flat borders for the edges of the puzzle. The benefit is that you can scale it to any size and repeat without flaws. I've adjusted these corners, as well as editing the top, bottom and sides so that the image tiles without any break. It also had corners in the top and bottom rows that do not meet when tiling. Unfortunately the texture that Woodstock produced left large blank areas when it tiles.
This is an extension of Woodstock's Texture28 The reason I did this is because I like to work in large scale.
