Slimy Letters with Brush Pens!

In this quick tutorial, I want to share a fun, easy way to draw slimy letters. I first did this style 2 years ago and fell in love with the outcome. Since then, I've changed up the style a bit to help make the effect even more realistic, so let’s get started!

Here’s what you’ll need for this tutorial:

  • Pencil

  • Eraser

  • Mixed Media or Watercolor Paper

  • Black Fine Liner or Pen with permanent ink

  • Waterbased markers (yellow and 3 shades of green) I’m using Karin Brushmarker Pro in the following colors:

  • Yellow – Canary 166

  • Light Green – Apple 210

  • Mid tone Green -Grass 253

  • Dark Green – Lush Green 288

  • Water brush pen or a Paint Brush and water

  • Optional: Grey Marker, White Gel/Paint Pen

Step 1: Sketching

Use a pencil to lightly sketch out your letter or word in simple sans serif/block letters . These will be used as a guide in the next step when you're inking the letters.

Step 2: Outlining

Use your black pen to loosely outline the letters while adding drips. The letters should look very runny and drippy so you shouldn’t have any shape edges or smooth straight lines.

Step 3: Adding Color

Decide where you’re light source and shadows will be. My light source is in the upper left corner so my darker colors and shadows will be on the bottom right of the letters and the drips.

Add some yellow to the top of the letters, light green all across the letters and then add the mid tone green to the bottom.

Step 4: Blending

Use a water brush or a paint brush to blend the colors together.

Step 5: Adding Inner Shadow

Add a very small amount of the darkest green to the shadow areas (bottom right) of the drips and then to a few random areas of the letters. Then use your brush to blend that dark green into the letter. Use this color sparingly to make sure that it does not overpower the lighter areas. If you’re using Karin Markers, you can do this step while the colors are still wet. With other brands, I would suggest that you wait until the colors have dried before adding the dark green.


Step 6: Adding Details

You can use a white pen to add highlights to the upper right side of the letters and a grey marker to add the shadows on the outside of the letter.
