1.25 or 2L bottle
pink paint (you may need white to tone it down)
a canvas or piece of wood
Paint a random "branch" onto the canvas with the black paint. The lines don't have to be perfectly straight. I think it looks better if they aren't.
Mix the white & pink paints to get a nice pink color. I mixed 2 parts "hot pink" to 1 part white.
Dip the bottom of the bottom of the bottle into the pink paint.
Press the bottle bottom onto the canvas to create the flowers. I used an eraser tip to create the flower centers. Allow to dry & hang.
