Constraints: no cuts, no glue, MC allowed only for shaping or for preparing sheets, 1 or more sheets of paper (preferably), any convex format works... You should give us some insights about your creation.
As you may know or not, my nickname is papeRain, thus I chose for this monthly challenge a subject close to that: Let it Rain! Feel free to interpret it in your own artistic perception. I am looking forward to see every participation. Feel free to spread the word to every corner where some potential designer may hide!
A last catch: only the first successfully posted umbrella counts / all other umbrellas will NOT qualify as a participation, but I will look at them anyway. Have fun!

Edit: I was asked if painting is allowed and I decided that it is allowed, but please mention it in the description so that we can recognize traditional color change versus painting.
