For these very high windows, stationary relaxed romans needed to be made as long as an actual shade in order to get enough fullness.
The fabric was a railroaded stripe so it had to be pieced horizontally, something we usually try to avoid. First the ring locations were planned so we could place the seam where it could be hidden in the permanent bottom folds. The woven pattern washed out when sun came through, so we interlined these, using regular interlining inside and dim-out lining on the outside. The dim-out also helped hide the seam.
