Here are the blueprints for an easy costume for Bob the Builder wanna-bes.
Cut the sleeves off an old flannel shirt and wear it over a long-sleeved thermal shirt.
Strap on a tool belt, add some old hand tools, and smudge on brown face paint for a hard-working look.
Hand the builder a pair of work gloves, a hard hat, a tape measure, a toy walkie-talkie, and work boots, and he'll be ready to tool about the neighborhood.
