Diamond Tufting the fainting couch
The way I envisioned the seams was that they would follow the shape of the diamond. So, for my couch, the spacing between the buttons (horizontally) is 3" and vertically 9" (measuring center button to button and *not* yet accounting for the depth of the foam).
So the zig-zag seam would lie in a horizontal line, but within the depth of the tufting? I think that's how we'd want the seam, so an opportunity would exist to hide it under a fold?
Now to actually arrive at the precise pattern to do that isn't exactly making itself obvious to me.
