Help!?
What can I use if I don't have a fine-tip black marker or a ruler listed in the materials?
If you don't have a fine-tip black marker or ruler, trace final lines with a thin gel pen or ballpoint and use the straight edge of a book or a piece of cardboard as your ruler while sketching with the pencil.
My bridge sketch looks messy or the marker smudged—how do I fix it?
If lines are messy or the marker smudges, keep your initial pencil lines light, carefully erase extra pencil marks with a clean eraser before tracing, and test the fine-tip black marker on scrap paper to avoid smudging when you trace the final lines.
How can I change the activity for different ages?
For younger kids, draw a simple footbridge with chunky crayons and big shapes and add a large hidden animal as the surprising detail, while older kids can design a suspension or arch bridge with accurate cables, refined pencil lines, shading, and detailed glowing lights.
What are some ways to enhance or personalize my finished bridge drawing?
You can personalize and extend the project by adding glued craft items for texture on pillars, using watercolor washes before tracing to make glowing lights pop as your surprising detail, or turning the scene into a paper diorama with cut-out components and extra color.
