I would argue with you if you accused me of being obsessed with monograms, but I sure do make a lot of them!  This was an easy one using a $2 white R from Michaels.  I first used green craft paint to cover the letter and then gloss ModPodge to give it some shine.  Piece of cake!

I then used a Sharpie pen to draw a small vine over parts of the letter.

Voila and done!
