Picture of brain thinking

How do you show a picture of a brain thinking?
This has been a "breather" day- busy thinking and calculating and cutting new work.
Naturally this has not gone so well- the gorgeous job we're about to start had a few changes which means we're just a little short on fabric and trim. There's more trim available, but the fabric is nearly gone.
(I know, I know)
The search is on for more- that's not my department- but at the same time I'm busy here trying to determine the alternatives in case more is not available.
This takes a lot of brain work! I took a picture of my notes on the job. It's 2 hobbled shades, and 2 pair drapery with bullion fringe in the lead edges and hemlines. I've figured both out several ways, depending on how much (if any) extra yardage the decorator can find. I'm just waiting for that phone call.
Why scribbles on plain paper???
I'm too old to do things differently- I learned to figure with a pencil, paper, brain, and calculator- work order forms just don't work for me, though I've tried. I always come back to scribbling by hand and calculating by brain with a little help from the same calculator I've had for 20 years.
You gotta enjoy numbers and manipulating them to enjoy this job.
And that's what we're working on today.
So since I can't take a photo of my brain thinking, I've put up a very very old picture of one of my favorite window treatments ever. It's so old that the picture was taken with (GASP!) FILM. The photo was scanned into, like, 3 computers ago, and keeps getting transferred with each new computer. It's a bad photo- grainy- but the treatment is SO lovely!
The Bordeaux valance (pattern from M'Fay) is one of my all-time favorites. It can be modified in a million ways to meet all kinds of window treatment challenges.
