My way would be to collect a selection of bright colours for the brick work at the top and base.
Boats with paper. Rectangle 2inches by 6inchea fold the ends base an inch from the corner on the base onto create the shape in pictUre.
On paper using the corners up 6 inches along base 3inches join dots should be a right angle triangle
On another corner up 4inches and along 2 inches. Join dots and make another right angle triangle
Play with these shapes to make the boats us heat and bond light stick on a background and zigzag edges.
Then on strip of large risk rack.
Hope this helps I know what I men hope you do.
