The hard one. Seeded from Brett's listing-blueprint, number 188 on his board. This starts from what a blueprint is: an architect's sheet. Blueprint blue with a faint drafting grid and the paper's grain, a double-line frame inset from the edge. The drawing in white line work, a floor plan or a front elevation, with its walls, doors, windows, room names and dimension lines, drawn in code. The sheet's title under the drawing in a drafting hand, the notes under it in a condensed technical face. A title block in the bottom right corner, ruled like a real one, carrying the lockup, your name, credential and phone, your picture as the approving signature, the sheet number, the date and the county. A revision stamp top right carrying the job.
The hard part. Not the drawing. Carrying a thank-you and a holiday on a blueprint without it turning into a listing gimmick. So the drawing changes with the job: the plan for a tip, the elevation for a market note, the porch drawn large for a thank-you, the table drawn in the dining room for Thanksgiving. Pass or note each by name, and say whether the last two hold.
