You’ve opened your kit. The pieces are waiting. You’re ready to turn a stack of paper into something rather wonderful.

Before you dive into the main model, there’s one little build we’d love you to meet: your practice kit.

Every Yona DIY kit includes one. And if this is your first papercraft adventure, we strongly recommend starting here. Think of it as a friendly rehearsal—with fewer pieces and absolutely no audience to impress.

A little practice. A lot more confidence.

Paper looks simple. Fold it, glue it, done. Then you meet your first mountain fold and suddenly the paper has geography.

Your practice kit gives you a chance to get familiar with the whole process before starting your main model: reading the markings, folding in the right direction, finding matching edges, and bringing flat pieces together into a three-dimensional shape.

You’ll discover how much glue feels right, how long a join needs a gentle hold, and how to line up those little corners. Small things, yes. But they make the next build feel much more familiar.

The goal isn’t a perfect first model. It’s knowing what to do with the next piece.

Find your fold–glue–“oh, I get it” rhythm.

Read through the included instructions before you start, then work through the practice model in the suggested order. Give yourself a clear space and permission to take your time.

1. Get to know the markings

The letters and numbers identify pieces and matching edges. Look for the same edge number on the pieces you’re joining, and use the assembly diagrams to check where they belong.

Those little markings are there to help. You don’t need to memorize them. This is crafting, not a surprise exam.

2. Practice the folds first

With the printed side facing you, circle-marked fold lines are mountain folds; the others are valley folds. Check the diagrams and pre-fold the pieces before reaching for the glue.

A moment spent checking the direction now is much easier than negotiating with a glued corner later.

3. Try the fit, then add a little glue

Bring the matching edges together without glue first. Check the numbers, the direction, and how the tab will sit inside the model.

Apply a thin, even layer of glue to the unprinted side of the glue tab. Join the matching edges carefully and hold them gently until the bond can support itself. Work one join at a time.

More glue doesn’t mean more success. Sometimes it just means more glue on your fingers.

Little mistakes are welcome here.

A fold goes the wrong way. A tab ends up somewhere unexpected. It happens—and this is exactly why we include a practice kit.

Here are a few things to look out for before you start the main build.

Mountain and valley folds get mixed up

If a section seems to bend in the wrong direction, pause and check its fold marks from the printed side. Don’t force the shape to fit. A quick look at the instructions is part of the process.

The printed side ends up outside

Matching the numbers is only part of the job. The pieces also need to face the right way. If letters and numbers are showing on the outside, check the orientation and fold directions before adding more pieces.

The glue tabs are showing

Tabs belong inside the model, tucked behind the neighboring face. Gluing them over the outside leaves visible overlaps, even when the matching edges are correct.

If you spot something while the glue is still workable, gently adjust it. If it has already set, don’t pull hard and turn one small hiccup into a larger one. Take a moment to understand what happened and use that knowledge on the next join.

A slightly wonky practice model can still do its job beautifully. It has taught you something.

Finished? Give it a little personality.

Once the glue is fully dry, take a moment to admire your first build. A flat sheet has become a little paper sculpture. You did that.

You can leave it white and enjoy the folds and facets—or make it your own with color.

Try colored pencils for soft strokes, water-based markers for bright patches of color, or crayons for a playful, textured finish. Support the model gently as you work and use a light touch, especially on the smaller panels.

Rainbow ears? Absolutely. Every panel a different color? Go for it. Your practice model doesn’t have a dress code.

Ready for the main build?

Before you move on, give yourself a quick check:

• I can find matching edge numbers.
• I know how to check mountain and valley folds.
• I try the fit before adding glue.
• I apply glue to the unprinted side of the tab.
• I keep the printed side and glue tabs inside the model.

If those feel familiar, you’ve already made a great start. Keep your instructions nearby, take the main model one piece at a time, and let your confidence grow as you go.

And if something leaves you puzzled, email us at support@yonadiy.com. A photo and your kit’s model name will help us understand where you are in the build.

You don’t need to arrive with expert hands. That’s what the practice is for.

Start small. Enjoy the next fold.

Happy building,
