Our featured artist calls Nottinghamshire, England home. Carol says “it’s in an area that was part of Sherwood Forest…Robin Hood Country!” Carol hides most of her painted rocks but does have a few keepers too!

She painted her first rock back in September of 2018. She says “my first efforts were using Sharpies that smudged & ran when I varnished them.” As with all newbie rock painters, it only takes one time to mess up a rock, before learning and moving on.

What types of paint brushes to use for watercolor painting on rocks?

Carol says, “any brushes will do although, I do prefer to use short handled ones. I have a few short handled travelling watercolor brushes that I’ve had over 20 years…. but I also use a really cheap disposable eyeliner brush too!”

Watercolor Supplies

  • Watercolor pencils
  • Paper towel to remove excess water from my brush
  • Any old jar or container to hold water
  • Pencil
  • Colored pencil crayons to add a little extra dry color where and when needed
  • A black fine liner pen
  • Plasticine to hold my rock steady
  • An old toothbrush & a kebab stick to Splatter paint onto my rock

Best types of rocks for watercolor rock painting

Carol says “Any rock will do, but as I find all my rocks, I can’t be picky.  Smooth flat rocks are great but pitted rough rocks gave a lovely texture to the painted doodle birds, butterflies, and etc. 

I love to walk and I get all my rocks on my walks over and around fields, woods, country lanes, byways & footpaths. I then stagger home with them in my rucksack!”

Watercolor Painting Step-by-Step Process

  1. Base coat. I use masonry paint t step pots which I apply with a nail polish brush … I cleaned and reused one from my nail polish bottle!
  2. I add light marks with a pencil so I can see roughly where my design will be on my rock.
  3. Then I paint the design.
  4. When dry I outline using a black fine liner pen & sign my rock.
  5. Varnishing is next. I use a yacht varnish which I apply with another cleaned nail varnish brush. Before you ask, I don’t live anywhere near the sea! Yacht varnish is available from DIY stores here in the UK to use on any outdoor project.
  6. When dry I add my details to the back of the rock and varnish that side too.
  7. Hiding is the next step….. and the hope the finder will not only like the rock but will post a photo to Facebook!

Watercolor Painting Tips for Beginners from carol

  • Firstly, have fun!  Paint the things you like …. I love painting flowers and other things in a loose style.
  • Don’t judge your rocks harshly…. remember all painted rocks are fabulous! I get really excited when I find a rock with a few scribbles on it!
  • Forget about coloring within the lines …. let your creativity and your paints flow, mix & spread. When outlining using a black fine liner pen. Keep your marks loose and free.
  • Don’t try to keep to just the painted areas.
  • Sit in a comfy chair, listen to your favorite music or tv show…. or like me listen to an audio book whilst I paint with a glass of something nice & fizzy to hand….. in my case a glass of lemonade!

Tweeter Bird Watercolor Painted Rock

watercolor bird painted rock

Easy watercolor ideas for rock painting.

Materials

  • Rock
  • White Acrylic Paint
  • Watercolor Pencil
  • Paintbrushes
  • Fine Liner Pen

Instructions

  1. With a pencil lightly draw a line for the branch. I want the redder hues to be on my birds chest. Starting from the top left I added fuchsia, then cherry, then teal green then iris blue. In a sort of oval shape with the tail. Most of the color overlap each other in a random way, When we add the water they will mix and blend together and hopefully there’s some random new combinations of colors. watercolor painted bird rock
  2. Using a paintbrush and clean water activate the paint allowing the colors to flow. Don’t’ try to be too precise, random is good! Activate the lighter areas first and then clean your brush. Do this between activating each color to avoid muddying the colors. Don’t’ let the paint dry in between activating each color though as we want them to mix and blend a bit. Then add some brown tones to the branch. watercolor bird painted rock
  3. Activate as before. watercolor bird painted rock
  4. Outline using a black fine liner pen. Keep your marks loose and free. Don’t try to keep to just the painted areas. watercolor bird painted rock
  5. Add details. I used a white acrylic paint pen to add the dots. Sign your rock and you’re done!watercolor bird painted rock
