- Who is the Roasting Vegetables poster for?
- Roasting Vegetables belongs to the Kitchen section rather than to a school year, because food is not something one grade owns. Anyone learning technique can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Roasting Vegetables poster?
- High heat, enough oil, one layer, plenty of space. Crowding steams them. A wall chart earns its place by being glanceable from where the work is happening, so Roasting Vegetables belongs on the wall where that food work actually happens, within glancing distance, rather than filed away.

- What size does the Roasting Vegetables poster print at?
- Roasting Vegetables is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Roasting Vegetables loses nothing.Printing guide
