Customize this cool spacecraft with extra hatches, portholes, side fins, and more. To make one, roll a rectangle of scrapbook paper (ours is about 4 by 6 inches) into a cylinder, sealing the seam with washi tape. Cut four 1-inch-long slits into one end of the cylinder, spacing them evenly around the edge. Cut out two mustache-shaped fins (A). Fold them at a right angle as shown, and insert them into the slits (B). For the nose cone, cut out a half circle (ours is 41/2 inches in diameter), roll into a cone, and seal the seam with washi tape. Run glue along the cylinder’s top edge and place the cone on top; let glue dry. Glue a rectangle to the rocket's side for a hatch.
