I really like this! I wish you had a tutorial here of how you did it.
I think it's 3 dimensioned.. cut two or three raindrops from different coloured construction paper and fold them each in half.. Then staple the raindrops together from the folded area.You can do this for the cloud too.. I made a craft similar to this, but my craft was an air baloon. you can follow the same steps for the air baloon craft too.I saw the craft from this link. http://pinterest.com/pin/68468856804346048/I hope this helps :)
Thank you for sharing, and a different idea.
