I have a diorama due in one week, and I need to make a chain link fence. How do/Can I build it without metal, or wire?The size should be 10 by 6 inches.

Wooden sticks, balsa wood or dowels or large cotton swabs with wooden handles. The latter is used in laboratories.

Spot welding welding rod, but that uses metal. Soldering copper wire, but that uses metal.

You could possibly do it using a mortising jig (makes square holes) in a drillpress and a small piece of balsa wood

Clear plastic and pine striping tape.

Some ideas.
