Gelatos. They are awesome. If you haven't used them, do yourself a favor and buy some! Then look up tutorials on how to use em! I blend them with water to use for background colors in this example.
My acid free markers, assorted flower and leaf stamps, watercolor paper (I cut into small squares) and thin paint brush
"Paint" the stamp you would like to use as a vase for your flowers.
Jar vase stamp on the watercolor paper
You want to start with the tall flowers first (kind of like actual flower arranging). You don't want a clean stamp like the jar...so paint the stamp again and stamp 2-3 times
If the color isn't dark enough for you, add some with the marker or the gelatos
Get a tiny bit of water on your brush and with tiny quick strokes, blend the flowers
How to color the stamp and press it on your paper
Creating the watercolor effect
Keep adding flowers to your bouquet
Now start adding foliage
After you are done stamping the bouquet then start to brush over the vase with water and add color to the edges if you like (I added a bit of gray)
Draw in some lines for the ground and brush with water. Then add some grass and pebbles
Don't forget your autograph
