    Watercolor Bubbles Artistic Envelope Tutorial

    This artistic envelope concept is one of my all-time favorites. It requires a bit of time and spontaneity (there’s no set formula for properly positioning the bubbles), but the eye-catching result is worth it! Put on your favorite playlist or podcast, pull out your watercolor palette, and enjoy.

    1. Prepare Your Watercolors for Making an Artistic Envelope

    Begin by moistening the following colors in your watercolor palette with water: red, orange, blue, and purple. Then, moisten a pan of Finetec Arabic Gold. There’s no need to pull out your artist-grade watercolors for this project: a simple watercolor set like the Prang palette pictured below will work great!

    A blunt art syringe is excellent for moistening watercolors.

    2. Add Watercolor to Your Envelope

    Now, get out a high-quality white envelope (try one from Cards and Pockets). Use a large paintbrush and random strokes to apply plain water to the left side of the envelope. While the water is still wet, load your brush with any color of paint, then touch the brush to the water. The watercolor will immediately start to bloom!

    Watercolor Bubbles Artistic Envelope Tutorial
    I used a size 6 paintbrush to create this envelope art.

    Continue to apply the brush’s tip to the wet water on the envelope using each color that you moistened. As the individual paint colors spread, they will naturally blend. If your water starts to evaporate, feel free to brush on more. Once all the water on the envelope has color on it, allow the envelope to dry. It’s okay if it bubbles up a bit in the process.

    Apply a mix of all of the watercolors that you moistened — including the Finetec gold — to the envelope.

    3. Add Bubbles

    Once your paint has dried, use a fine-tipped black pen (I like the Pilot G2 05) to draw random sizes of connected circles on top of the paint.

    Watercolor Bubbles Artistic Envelope Tutorial
    Make sure your watercolor has completely dried before you take on this step! Otherwise, the ink won’t go on well.

    There isn’t a particular pattern that the bubbles should follow. I do have a couple of tips, though: first, vary the bubble sizes. Most bubbles should be small, with plenty of medium-sized bubbles mixed in and a few large bubbles here and there. Second, don’t draw bubbles outside of the watercolor. Third, try to cover 1/3 of the watercolor area with bubbles. Less than that will look too sparse. More than that will overpower the watercolor.

    Here’s an example of what your watercolor bubbles artistic envelope might look like at this stage.

    4. Add an Address

    Now, use a pen to write your recipient’s name in George Style lettering. Instead of filling in the George letters with diagonal lines, however, use bubbles.

    Watercolor Bubbles Artistic Envelope Tutorial
    You can either us the same pen you used for the bubbles to write the recipient’s name, or you can use a different one. I switched to a Micron pen for this step because G2 pens tend to smudge if you erase pencil guidelines around them.

    Next, use Janet Style calligraphy and sumi ink to write the recipient’s address.

    Elegant Janet Style calligraphy provides a nice contrast to the rest of the envelope.

    5. Apply Postage to Your Artistic Envelope

    Finish up this envelope art by applying postage that echoes the colors that you used in your funky motif. If you can find it, the Janis Joplin Forever stamp that USPS released in 2014 is a perfect fit … it’s available on eBay. Otherwise, the USPS store always has something cool!

    You can read more about making postage stamp collages and where to find the stamps to make them in this article.

    6. Send

    Once you’ve affixed your postage, it’s time to give your envelope one last appreciative gaze, slip a letter or a card inside, and send it on its merry way!

    These bubbles are just so fun to look at!

    While this tutorial gives you a specific color scheme, you can endlessly customize the watercolors that you use to reflect your mood or the season. For example, I used autumn colors to make this mail art in October a couple of years ago:

    This envelope utilizes a fall color scheme, a Jimi Hendrix stamp, and whimsical Kaitlin Style calligraphy.

    No matter what color scheme you choose to use, you can bet that your artistic envelope will be cool! I hope that you enjoyed the tutorial and that it inspires you to get to creating. Thanks so much for reading!

    Warmly,

An X-Acto knife (aka a hobby knife) is one of thos An X-Acto knife (aka a hobby knife) is one of those tools that is indispensable for a lot of applications. It was designed to make precise cuts, which, of course, it does well! But, you can also use it to scrape off unwanted ink smears (pro tip: after the fact, you can smooth disturbed paper fibers with a pebble), create interesting interior cuts, trim tiny details that scissors can’t reach, make stencils and templates, refine collage elements, and gently correct small drawing or calligraphy mistakes.

I have used X-Acto knives for many TPK Blog tutorials, but up until last week, I’d never written a guide that puts the X-Acto knife front and center. That guide now exists, and you can find it by visiting the link 🔗 in my profile. Be sure to watch the tutorial video!

Hard to fit everything in, but this was 2025 in a Hard to fit everything in, but this was 2025 in a nutshell at TPK! 🥜

This year, I loved teaching at @thehappyevercrafter’s Workshop Week and participating in @calmingcalligraphy’s World Calligraphy as Meditation Day. And seeing the TPK calligraphy kit featured in @newyorkermag’s 2025 holiday gift guide was an unexpected (and delightful) cherry on top! 🍒

So much of what happened over the past year, though, was shaped by the TPK Premium community. Their questions and feedback helped guide Hand Lettering 101, while their encouragement fueled tutorials on topics ranging from turning red wine into calligraphy ink to illustrating recipes, painting with a wedge brush, and creating greeting cards and envelope art. 💌 That same support made it possible to create new worksheets and resources that others were able to enjoy as well, which I’m very grateful for. 

For a fuller recap (with helpful links and details) I shared a 2025 reflection on the TPK blog (link in bio).

✨ A little comparison today … because not all ✨ A little comparison today ... because not all golds behave the same.

✦ Finetec gold → bright, cheerful, and versatile
✦ Greenleaf & Blueberry faux brass → softer, muted, and stunning
✦ Yasutomo pale gold → velvety, subtle shimmer with a sensible amount of sparkle

I love having all three on hand and choosing based on the feel I want for a project. It’s tough to go wrong! ✨
