The time came today to commit myself to the revisions needed on my windows project. The problem was, however, how to design the half-dozen revisions needed, and to prepare copy of these to pass to the glass technician, without having to redraw completely the entire design. I hit upon an interesting trick.
I laid over the original designs, small sheets of tracing paper (parchment quality), and drew in pencil the outlines of the parts that were to be altered. I then marked on the parchment with a black marker pen several reference points in the original design, so that I could return the copy to its correct position when altered. Then I drew the new, revised designs onto the pieces of parchment, in black ink, and coloured them in appropriately with coloured pencils, to match the original shades as much as possible, where necessary. (Where the new colours needed to be different from the old, of course, they could be given the new colours.)
I then checked the alignment, by replacing the pieces of parchment over the original designs, and gave them code letters.
When I was satisfied both with the new designs and the accuracy with which they could be repositioned, they were scanned for reference purposes. Small scale prints of my own original photographs of the window designs were printed, and on these prints I marked in red ink the positions of the new sections, together with their code letters. These will then be passed to the glass technician, guiding his revision of my original designs. I think it’s going to work OK.
With one exception the revisions have been minor, such as details of uniforms. The big change was in the figure of the bomb disposal operative, where I had to redraw the figure to make it less ambiguous, and I had to replace the American equipment I had originally copied from the internet, with “proper” British equipment.
I hope that on Saturday, when I hand all this over, I will be able to say that it is (as far as I am concerned) finished.
