Begin by folding a sheet of card stock in half. Next, cut out half of a balloon shape along the fold.
Repeat step 1 so you end up with 4 balloons. If using patterned paper, make 2 solid and 2 patterned.
Glue one side of a patterned balloon to one side of a solid colored balloon, alternating them to create an accordion shape.
Keep gluing until all 4 pieces of paper are attached. Make as many balloons as necessary.
Fold a piece of white card stock in half and cut half a cloud shape along the fold. Cut as many as you want. Repeat steps 3 and 4 until the clouds are attached and have an accordion shape.
Glue the balloons and clouds onto a rectangular piece of blue card stock, for the sky. Next, cut a small rectangle out of patterned paper in a contrasting color and glue down a few inches beneath each of the hot air balloons. This is the balloon basket.
Use a black marker to draw 2 lines attaching the balloon with the rectangle to form the basket and ropes.
