Heart painted rocks are some of my favorites to leave out as kindness rocks. They are great around Valentine’s Day, but can be left out all year long!

Mosaic Heart Painted Rock Supplies

I am using paint pens for these stones. I like how easy they are to work with. However, you can get away with filling in your colors with acrylic paint and a toothpick as well. A brush is hard to get all the points filled. Having a black extra fine tip paint pen, like the Posca I am using in this tutorial, makes this process a breeze! Find all of these supplies, including the rocks I have in this tutorial in the link below.

How to Paint Mosaic Hearts Step-by-Step

Below you will find step by step images on how to paint this design. There is a full video tutorial after if you are looking for more details or tips!

Start by laying out your heart outline. Next, break the heart into a bunch of smaller sections. Pick a few colors and start filling it in. I avoid having the same color touching side by side. Points touching is going to happen a lot. So work small amounts at a time switching between colors. You can add in more lines if needed! I’m using my glitter Posca pens which gives it a fun shimmer.

Let you colors dry then begin lining all of the sections with your black extra fine tip paint pen. I like to make the edges along the heart curves into straighter lines as well.
