I coordinated efforts between design and fabricating personnel to ensure that the pattern was aligned between these two treatments.
Once the cornice pattern placement was determined, the shade was planned, from the top down which is sort of backwards, to me. It was precisely plotted out on graph paper, and the specifications noted on the fabric selvedge. The cornice placement was indicated, then the shade began 3/4" below that.
When fabricating shades to pattern, it is the pattern that is important, not the
actual measurements. You need to think in terms of repeats, not inches.
Especially with any embroidery, the repeat can vary slightly from one to
another, so you work from point to point.
