There are so many fun watercolor techniques for kids to try! Take a look at my collection of watercolor painting for kids for more fun and creative ideas.

Using liquid watercolors for this project really makes the colors bright and bold. Kids can add their own fun spooky touches to their painting like spider webs, a black cat, pumpkins, bats, or a crescent moon making each project unique!

Supplies

Watercolor paper or white cardstock
Liquid watercolors or a watercolor paint set
Paintbrushes
Paper straws
Wooden board and painter’s tape (optional)
Paint palette and water dish
Pencil and eraser

Instructions for your Halloween art project

1. First, prepare your watercolor paper. I like to tape our paper down to a wooden board, this helps with the paper sliding around and also helps it to dry flat.

If you don’t have a wooden board or are doing this project in the classroom, you can simply skip this step or try taping the paper down to a desk.

If you do not have watercolor paper you can also use white cardstock, but the colors might not blend together as nicely.

2. Get your paint colors ready for the sky. Have kids choose 3 – 4 colors for this part. We used liquid watercolors but a regular watercolor paint set would also work.

Test your colors first on a scrap piece of paper to make sure they are bright enough. Watercolors will always dry lighter.

Paint your paper with clean water first. You want the paper to be wet but not soaking. If you are using cardstock, you will skip this step.

3. Start at the bottom of your paper and using a flat brush, paint your first color onto the wet watercolor paper. Clean your brush and paint the next color right away.

You want to paint the background fairly quickly. The wet paper and wet paint will mix together and create a soft blend between colors.

This is called a wet on wet technique. Take a look at these 5 easy watercolor techniques for beginners for more details.

4. Once the background has completely dried, kids can draw their Halloween silhouettes with a pencil. Remind kids to press lightly so if they need to erase anything it won’t ruin the background.

Start by drawing the tree trunk on the side, add the hill, and then kids can add their own special spooky touches. I drew pumpkins and a black cat for the examples but kids can choose to include anything they like.

5. Using black watercolor paint and a round brush, paint in the tree trunk. To create the branches, use a paintbrush to put a fairly big drop of paint down where you want to start a branch and then blow through a straw to create the branch.

This technique will create branches in different sizes that go in all directions, making the tree look extra spooky!

I find that cutting the straw in half works well for this. You also want to make sure that you put enough paint down on the paper for the blow painting to work properly.

Keep creating branches using the blow painting technique until you are happy with how your tree looks.

6. Use black paint to paint in your details at the bottom of your painting. Have kids use a smaller round brush for this step.

7. Once the painting is dry, try drawing in a spider web or two in the tree branches! Use a pencil to draw them in first and then paint over top of your pencil lines with black watercolor and a small detail brush.

Carefully remove the tape from around your painting after everything is completely dry.

Instructions

First, prepare your watercolor paper. Tape your paper down to a wooden board with painter's tape. This helps to keep the paper from sliding around and also helps it to dry flat.
If you don't have a wooden board or are using cardstock, you can skip this step.
Have kids choose 3-4 colors for the sky. I used liquid watercolors but you could also use a regular watercolor paint set.
Start by painting your watercolor paper with clean water. If you are using cardstock, you can skip this step as well.
Use a flat brush and paint the sky one color at a time. Let the wet paper and wet paint blend together to create soft lines between the colors.
Let everything dry completely before moving on.
Use a pencil to lightly draw in the tree trunk, hill, pumpkins, or black cat and any other Halloween details that kids want to add.
Start by painting the tree trunk with black watercolor paint.
To create the branches, use a paintbrush to put a fairly big drop of paint down where you want to start a branch and then blow through a straw to create the branch. Keep creating branches using the blow painting technique until you are happy with how your tree looks.
Cutting the straw in half makes this process a bit easier. You also want to make sure that you put enough paint down on the paper for the blow painting to work properly.
Paint in all of your other details to your Halloween silhouette painting, including any spider webs in the tree branches.
Carefully remove the painter's tape from around your paper.
