If you looking for a fun proposal idea, this might be it. Take a long walk in the park and suggest your partner to make a fun portrait together. When you reach the artist, he will already have your portrait made, but of course, she wouldn’t know about it. So you will pose for 5 minutes, and artist will ask if you want to take a look at the drawing. He will turn the picture and she will see a portrait of you on one knee, at that moment you propose. Fun proposal and you will have this drawing for the rest of your life as a reminder of your proposal.
Ideal places for this proposal: Central Park, Brooklyn Bridge Park, Washington Square Park.
