Apparently skinning window frames isn't as easy as skinning say, the taskbar or even the start panel. I opened various parts of the window frame of the Diamond style but each part is is doubled ( one for the selected frame and the other for non-selected frame, i know). But I tried opening each of the four parts that make up the frame and on a new layer in photoshop I tried to piece them together so I can create my own frame style using the measurements of those from the Diamond style. But the four parts, when pieced together, dont match up properly.

i hope i dont have to create each part of my new style of frame seperately. Because I want the images in the finished frame (both selected and deselected) to fit perfectly and look as one smooth complete frame when applied. 

If I were creating a frame that was just one solid color, this wouldnt be so much of an issue. But the frames I am working on are PATTERNED and have shiny glares on them that overlap over the multiple parts that make up the entire frame. So my question is:

Is there a SPECIFIC tutorial that deals with creating intricate/detailed frames? If so, please post a link.
