Step 6

Put your marker tip on the starting point and draw the whole image without lifting your pen until the main picture is complete.

Step 7

Add imaginative details as you draw by looping crossing and weaving your line while still keeping the marker down.

Step 8

Make lines bolder by tracing along or next to them while keeping your pen on the paper to thicken shapes.

Step 9

Let the marker dry for a moment then gently erase any pencil guidelines you can still see.

What can we use if we don't have large drawing paper or a marker from the instructions?

Tape two printer pages together as your 'large paper' using the 'Tape your large paper flat to the table' step, and substitute a felt-tip pen, gel pen, or crayon for the 'Put your marker tip on the starting point' instruction.

My line keeps breaking or the page slides while I draw—how do I fix that?

Follow 'Practice a few small one-line drawings on scrap paper' to steady your hand, make sure to 'Tape your large paper flat to the table' so it doesn't move, and 'Let the marker dry for a moment' before erasing to avoid smudges.

How can I adapt this one-line mega challenge for younger or older kids?

For younger kids simplify by 'Lightly sketch big shapes' and use a thick marker to keep the line continuous, while older kids can use the full instructions to 'Add imaginative details' and 'Make lines bolder by tracing' for more complexity.

What are some fun ways to extend or personalize the finished one-line artwork?

Extend the project by taping extra sheets to create a mural as in 'Tape your large paper flat', add patterns and color with your 'coloring materials', or photograph and 'Share your finished mega one-line artwork on DIY.org' to personalize the outcome.
