    If you’ve been craving a project that’s creative, quick, and a little different, you’ll like this tutorial. Today’s accordion-fold watercolor card is as fun to make, and it looks just as pretty standing up as it does laying flat.

    Mountain-themed birthday card

    I love to send cards that are engaging, tactile, and don’t look like anything you might find in a store. Today’s card checks all the boxes:

    • It’s an irregular size (send it in a #10 envelope).
    • It features a lot of texture and visual interest.
    • Thanks to the trifold design, this card opens into a scene that can stand proudly on a shelf or desk.

    When you untie this card, it stands by itself.

    You don’t need a lot to make this project—just a few tools and a little time. Here’s what to gather before we get started:

    Supplies needed to make greeting card
    • Piece of watercolor paper (affiliate link) cut to 9″ x 11.75″ (~22.8 cm x 29.85 cm)
    • Pencil + eraser
    • Ruler
    • Scissors
    • Bone folder (affiliate link)
    • Watercolor palette of your choice (I used a custom Greenleaf & Blueberry palette)
    • Size 3 paintbrush (size is approximate; use whatever large-ish size you have on hand)
    • Jute twine (affiliate link)
    • Optional: pointed pen and nib to write a greeting

    1. Cut Your Watercolor Paper

    Start by using your ruler to draw a diagonal line. Begin from the upper left corner of the watercolor paper and draw to the middle right.

    Then, cut along that line.

    2. Make an Accordion Fold

    Once you’ve cut the watercolor paper, use your ruler and pencil to divide it into three even sections.

    Card with pencil marks
    Each section will measure just under 4 inches (~9.9 cm).

    Then, use your bone folder to make an accordion fold as shown below.

    Making one inward fold and one outward fold helps the card’s panels nest neatly together.

    3. Cut Mountain Shapes

    Now, fold your card together. Then, use your pencil to draw jagged mountain shapes on each section.

    Pencil mountain shapes
    Your shapes should be random and jagged.

    Next, use your scissors to cut out the mountain shapes.

    4. Paint Mountains

    Now, use a mixture of purple and blue watercolors to paint jagged connected triangles in all different sizes. (Once you paint a few, you’ll notice they look like mountains.) For a more finished look, I like to add mountains to the front and back of the card. If you’re short on time, you can just paint them on the parts that show when the card is folded.

    Painting a mountain range
    I used a mixture of Lapiz Lazuli and Ultramarine Purple to paint these mountains.

    Next, paint a few larger jagged triangles behind your first mountain range. If you have a nice turquoise or deep green tone, that’s a great color choice.

    Painting turquoise mountains
    These mountains were painted using Yucatan Mayan Blue.

    Finish up by filling in the remaining mountains with a warm gray tone.

    Gray mountains
    These mountains are a mixture of Slate and Graphite.

    5. Write a Quote

    Next, write a quote on the first panel using watercolor calligraphy. (It’s a good idea to make a pencil draft first, but you don’t have to.) For a cohesive look, stick to the same watercolors as your mountain scene.

    Writing a Kaitlin Style quote
    I used all-lowercase Kaitlin Style calligraphy to write “The best view comes after the hardest climb.”

    6. Write a Note and Fold

    Once you’ve calligraphed or hand-lettered a quote, use your everyday handwriting to write a note on the next two panels.

    Then, fold up the card and secure it with a piece of twine. Finish up by tucking it into a #10 envelope to send!

    I like to tie this card together with a piece of twine, but any nice ribbon or string would work.

    Inspiration and Variations

    This card concept was inspired by Phyllis Macaluso’s Staggered Floral Trifold Card Tutorial. I love the interactive aspect of that card, and I wanted to put a masculine spin on it. Mountains felt like the perfect way to give the concept a more rugged, nature-inspired look.

    Pair Phyllis’ tutorial with The Beginner’s Guide to the Triangular Paintbrush to make beautiful floral cards.

    Remember, there are plenty of possibilities beyond flowers and mountains. Anything that repeats beautifully or creates a sense of rhythm will work well—think leaves, cityscapes, stars, or seashells.

    Mountain-themed birthday card

    Thanks so much for spending a little time with this tutorial! I really enjoyed the rhythm of this project—cutting out mountains, layering colors, adding a quote, and tying everything up with twine. It’s one of those projects that’s satisfying from start to finish, especially if you’ve been craving something hands-on and creative. I hope you enjoy making it as much as I did!

    Warmly,

I experimented with using the chic poppies techniq I experimented with using the chic poppies technique (see my reel from a couple of days ago) to make pretty stationery. LOVE how it turned out! The poppies are just an elegant way to add personality and elegance to any paper good. If you’re a TPK Premium member, *definitely* check out Lesson 6 of the Beginner’s Modern Calligraphy Online Course (2025 version). In it, you’ll find a detailed video demonstration that shows you how to bring these poppies to life! ✍️

✨Chic Inky Poppies Mail Art✨ – This inky poppy ✨Chic Inky Poppies Mail Art✨ - This inky poppy motif is one of my all-time favorites for filling blank space with drama and elegance. To make it, you use dark ink smudges, loose leaves, and airy petals to build a border that looks intricate but comes together quickly. My go-tos for this style are sumi ink and a touch of gold watercolor for warmth. 

Want to try it yourself? Visit the TPK website (link in bio) and search for “Chic Inky Poppies Mail Art Tutorial.” Happy creating! 🌸🖋️

✍️ There’s a fresh addition to the TPK Catal ✍️ There’s a fresh addition to the TPK Catalog: The Graceful Ballerina Calligraphy Drill Worksheet 

This ballerina is unique among TPK calligraphy drills in that it’s really not that complicated. After a few simple loops, a flourished tutu, and long strokes to make the legs, you have, well, a ballerina! 🩰 The most difficult part is getting the outline right; but even that isn’t too bad because you’ve got a traceable outline included in your worksheet set.

The beauty of the flourished ballerina? She makes *anything* look elegant: cards, envelopes, gift tags, whatever. My recommendation is to feature her on your next envelope. She’ll add a “wow” factor and allow you to left-justify the address, which is always a relief (no need to bother with centering)!

To find her, visit the link in my bio, then navigate to the Blog!

✨I’ve been making these little calligraphy Chr ✨I’ve been making these little calligraphy Christmas trees for years. They’re a go-to whenever I need a quick gift tag, envelope flourish, or something festive that doesn’t require a whole afternoon.

They look fancy, but they’re really just simple strokes stacked in different patterns. Truly: once you get the rhythm down, you can make a tree in under 30 seconds. 🎄 

If you want to try them (there are six styles!), the tutorial is on the TPK Blog, and it’s called
“6 Simple Ways to Make a Calligraphy Christmas Tree.” Feel free to google it, or visit: thepostmansknock.com/6-simple-ways-to-make-a-calligraphy-christmas-tree/

It’s very beginner-friendly, video-based, and a great way to get some creativity in during a busy season. I hope you love it as much as I do. 💛

🎁 These printable gift tags are one of my favor 🎁 These printable gift tags are one of my favorite free printables on the TPK site. Just download, print, cut them out, and — if you want to — reinforce them with a bit of cardstock.

Inside the PDF you’ll find four designs: Festive Frida, Flourished Tree, Pine Boughs, and Merry & Bright. They’re all hand-drawn, and they make even the simplest wrapping look bespoke and artistic. 🎨 

Pro tip: If you’ve got a bit of extra time, add a pop of watercolor or some gold dots; and consider mounting the tag on a contrasting piece of cardstock for extra oomph.

They’re free to download at: thepostmansknock.com/free-super-cool-hand-drawn-printable-gift-tags/ (or visit the link in my stories today). Happy holidays!

There’s something extra fun about a card that do There’s something extra fun about a card that doesn’t just open … it comes to life. ✨ This little stand-up tree might look fancy, but it’s totally approachable — relaxing to make, satisfying to embellish, and (my favorite part) it folds up perfectly to pop in the mail. 💌🎄

If you’re looking for a holiday project that feels creative and doable, this is *such* a good one. The printable template does half the work for you, and you can customize the rest with flourishes, white ink, ornaments, or whatever feels festive to you.

The full step-by-step tutorial is waiting for you on the TPK website; just head to the link in my bio and tap “Blog.” I think you’ll have as much fun making this as I did. ❤️
