These pirate ships were created by one of my grade 3 classes. Students used plastic scrapers and wooden skewers to scratch patterns into wet painted paper. The aim was to create a wood grain texture in the brown and something to suggest the ocean on the blue papers. Once dry, we used the brown paper to fold an origami boat base. A piece of wooden skewer was added for the mast and paper sails and flags were cut from a template I made (students decorated them with Jolly Rogers etc).
We used one piece of blue patterned paper to cover a piece of cardboard for the base. Students then had to sculpt the rest of the blue paper into waves. I just love the way they have cut, twisted and curled the paper to suggest the movement of the ocean.
