Apple Barrel Craft Paints Check Price on Amazon

I decided to bring out my craft paints for this! I wanted to use all the colors in the rainbow and didn’t feel like mixing all my colors.

UPDATE: I recently redid this painting with the Liquitex BASICS acrylic paints and it turned out very similar, if not more vibrant than the Apple Barrel! So, yes you can use Liquitex on this painting and achieve similar color results!

This painting would make an excellent DIY unicorn paint party activity!  If you are doing it with a group, I recommend transferring the unicorn to all the canvases before the event to make things easier.

As always, don’t forget to share your painting on Pinterst or Facebook!

Step By Step Pictures

1. Draw Or Transfer Your Unicorn Head

Draw/ sketch out the unicorn lightly with pencil (see steps above).

It is only optional to outline it with sharpie. I did it for demo purposes only.

Also, you might want to practice drawing on a separate sheet of paper if you’re struggling with the drawing.

If you’re transferring, just print out the unicorn PDF and use graphite paper!

(note: graphite paper gets placed between the print out and the canvas then you trace on top. It will transfer to the canvas)

—->Note: I ended up changing the design of the snout at the end of the process pictures. The drawing looks slightly different in the following pictures but the instructions are exactly the same. 


2. Paint The Background 

Paint the background with a small flat brush.

I used bimini blue (bright aqua green) and white. I dipped my brush in both colors to get an inconsistent color.


Paint spirals in the background with a small round brush and parrot blue (light blue permanent). 


3. Paint The Unicorn’s Head White with some blue shading

Paint the unicorn white. I used a 3/4″ flat for this as well as the blue shading.

When you shade with the blue, blend it in with the white by applying both white and blue to the canvas. 

Add some shadow areas with white mixed with parrot blue (light blue permanent). Blend it in white the white.

Be careful not to add too much blue, just a little!

Paint the eye and nostril black with a small round brush.


4. Paint The Hair One Color Strand At A Time

With a small round brush, paint each stroke of hair separately, following the lines of the curves you drew.

I went in this order: fuchsia, orange, yellow, green, bimini blue, purple iris.

Slightly overlap colors to allow them to blend together. You can go back and blend the colors some more by using a smaller round brush and really blend the colors to get a rainbow ombre effect in the hair!

5. Outline Some Areas With Black

Use a small round brush and black to outline some areas of the unicorn to make them stand out.

Don’t outline everything, just a little here and there. 


6. Paint The Horn

Paint the horn gold or use a gold sharpie to color it in. If you want to get extra crafty here, add some gold glitter!


Outline ovals on the horn black (optional).

Add some white splatter paint over areas of the hair and horn with a toothbrush. This actually makes it looks like glitter but it’s paint! 

Also notice that I added more hair! Just over lap some of the strands to achieve this effect. Use a small round brush to get into really find details with the hair! 


7. Some Final Touches

As you can see, I fixed the unicorn’s snout by painting over some blue in that area!

I mentioned earlier that I changed the design of the head in the end and this is where the change took place! If you are using my traceable, then you don’t have to worry about this step.
