Hi everyone, four summers ago my aunt told me to paint her courtyard wall. She said that I was free to choose the design that I would want. I thought of something simple and decorative, with a harmonious color palette, since blue and yellow are colors that go well together. They also combine blue and pink.
I don't have a lot of photos, so I'll try to explain as well I can.

Supplies

Exterior paint for wall (white, pink, dark blue, blue, yellow, green, light purple).
Paint roller.
Brushes.
Newpapers or blanket to avoid staining the floor.

Step 1: Remove Dirt

As you can see this wall had a lot of dirt that came from the rain.

I only painted with a base white paint.

Step 2: Little Plants

I started with all green plants, I did this without sketch. With a straight-tipped brush of about 1 cm, I drew a curved line, from each line I drew a few more lines and on all the tips I made some little leaves.

Step 3: Sketch

I drew with a pencil the silhouette of the flowers that I was going to paint. It's a simple design, all people could do it. First, I painted all the parts that were going to have the same color.

Step 4: Keep Working

Little by little I added all the flowers and finally the details. I didn't paint the outline with black paint, I painted some outlines and details of the dark blue because it is the darkest colors.

Step 5:

Unfortunately, four years later or more... I know that the rain will dirty the wall again but, this way I have another opportunity to draw something new. I hope you like my idea.
