Thank you notes are a simple gesture that express gratitude for someone else’s kindness.

At times, purchasing them in bulk is most appropriate. But there are also times when creating little note cards yourself adds a special element to the mix – making this expression all the more significant.

In this tutorial, I’ll show you one way to make a sweet and simple watercolor thank you note using very little paint, and written in your handwriting for added personalization.

Simple Watercolor Thank You Note Supplies

For this project, I’m using an A2-sized note card and envelope. A2 note cards are 4 1/4 inches by 5 1/2 inches in size. And A2 envelopes are 4 3/8 inches by 5 3/4 inches. You can buy the cards pre-cut, or cut down your own watercolor paper.

I chose the latter. To create the card, I placed watercolor paper on a self-healing mat and with an X-Acto knife, I measured 4 1/4 inches, and then pulled the X-Acto knife down along my ruler. Next, I made sure the length of it was 11 inches. Lastly, I lined up the short edges, and then folded the strip of paper in half.

This makes for an oblong note card (landscape orientation) – the spine is 4 1/4 inches high. For portrait orientation, measure a strip of paper that is 8 1/2 inches long and 5 1/2 inches high, and then fold it in half.

I happened to already have kraft brown envelopes already on hand, so I have no instruction on how to make that. (Sorry – I’ll add that to the list of future blog posts!)

Watercolor Supplies

Now for the watercolor supplies. Anything will do, really. I used tube paints that were already in my ceramic palette – a mixture of carmine red and rouge. Choose any colors you wish.

My brush was a #2, I believe. The number has rubbed off with use, so I cannot confirm this, but the size brush you use will determine the size of your watercolor heart.

And of course you will need a jar of water to wet your brush, and a paper towel.

Writing Supplies

Any monoline, liner pen, or inking pen can be used to write, “thanks.” I used a “Stabilo point 88 fine 0,4” in black. It is *not* waterproof, so keep that in mind when choosing a pen.

If your pen isn’t waterproof, you’ll want to make sure it doesn’t touch the paint and it’s important to let the ink dry completely before erasing any lines.

You might want to pencil in a straight line on which to write, if so, a straight edge, pencil, and eraser will come in handy. Now let’s create our design!

Creating the Watercolor Marks

1. Dip your paintbrush in water and then load your brush with paint. You might want to dip your brush in more than one paint color as I did, or use only one color. It’s up to you.

3. Next, simply lay the loaded brush down on the note card and then pick it back up again.

4. Do this a second time in the opposite direction.

 
Et voilà! You just painted a watercolor heart.

Writing Out “Thanks”

And now we can officially make this a “Thank You” note card by writing out “thanks” beneath the heart.

In the first image, you can see that I drew out a pencil line in order to keep the word straight. I chose all lowercase printed letters. Prefer brush lettering or modern calligraphy? Have at it!

As a reminder, make certain that the ink is dry before you erase your pencil line! I was a bit hasty and had to create a new card due to smudging.

Now Write Your Interior Message

 

And that’s it! Simple, eh?

Now you can open up your simple watercolor thank you note and write a message inside.

Your recipient will be super grateful and you can be proud of yourself for making a simple but cute note card!
