I truly believe letter writing is a lost art. Doesn’t everyone love to receive letters in the mail? So I’ve started creating illustrated envelopes that can be folded and mailed to my family and friends.
Materials you will need:
I pulled out all my Tombow products for this project.
- Mixed Media or Watercolor Paper
- Pencil
- Tombow Dual Brush Pen
- Water brush
- Eraser
- Scissors
- White gel pens
- Ruler
- Washi tape or stickers
- Blending Palette
- Envelope Stencil (I use an old envelope…just unfold it and trace it)

Step 1
Trace the envelope stencil onto your paper and then cut it out. Fold your envelope so you know where your fold lines will be.


I’m going to be using my dual brush pens as watercolors today so I’m using mixed media paper. I love to use mixed media paper with dual brush pens, but you can also use watercolor or Bristol paper.
Step 2
Sketch your illustrations onto the inside of your envelope.


Step 3
Rub markers on the blending palette.

With the water brush I begin to add color like I do watercolor paint.

Step 4
You can write in text with pencils and then trace with pen…or you can write directly with pen. I like to start with pencil so I can reposition any text that isn’t fitting the way I want. Then I erase all the pencil lines.

Step 5
I like to add washi tape and stickers to close and seal my envelopes.
