As a small family design studio, we’ve had the joy of seeing these become some of our most popular nursery and kids room designs, chosen by families again and again this year. We hope they inspire what you create next.
Watercolor Rainbow Dots
Let’s begin with the star of the year. Dots! The humble dot took first place again.
Year after year, this simple watercolor pattern continues to be the design families choose most. We think it’s because our watercolor dots strike that rare balance: cheerful but calm, playful yet timeless. They make rooms feel happy from the very beginning, and just as joyful years down the road. Plus, they’re removable fabric wall decals, so you can reposition them easily (and install them in less than a naptime).
"Love how these turned out!! Exactly what I needed for my son's playroom! They truly look like I painted them on the wall!"

Modern Jungle Kit
In 2025, families chose these playful, watercolor jungle animals again and again. We think moms and dads were drawn to the storybook feel… though it might just be that the lazy leopard called to them. 😉
"So adorable and well made! Looks beautiful—just like someone actually painted the images on the wall. So easy to apply (and re-apply)!"
Alina ~ Knoxville, TN
Watercolor Clouds Classic Large
Our watercolor clouds are offered in two sizes... both made the best-seller list this year. Many families mix and match them to create a soft, dreamy sky that feels calm and timeless. They’re often chosen for their gentle watercolor texture whether floating on their own or paired with our Nursery Daydream Elephants, who drift happily among them.
Watercolor Dogs from the Pet House Collection
Another family favorite in 2025 was the Watercolor Dog Kit, painted in the Spritz color palette, inspired by time Julianna spent visiting family in Copenhagen and the fresh, playful colors that stayed with her.
We think families love this kit for its modern color palette, the watercolor textures that make it look as though it was painted in place, and of course, the love for all things pup. Some moms (hello me) have even used these to add a stylish upgrade to spaces for their fur babies.

Big Statement Favorites for 2025
These are the pieces families chose when they wanted to go big. Whether it’s a designer mom building a room around a single wall, or a nana gifting her newest grandbaby something unforgettable, these statement designs are made to lead the way. We think of these as big art to ignite little imaginations.
Extra Large Rainbow
We offer three different sizes of our watercolor rainbow, but this room-sized burst of color was the winner in '25. However, we have also discovered that all sizes of rainbow magic will make a child smile. And a grownup, too.
"I would give it more stars if I could. It surpassed my expectations. I get so many compliments on it and my son loved it."
Alexandra ~ El Paso, TX
The Feather Tree Kit
This one sings its way into hearts every year. With pattern-filled birds, fun modern birdhouses, and a tree that can grow as tall as you want it to, families loved building their own “perfect nest.” No two Feather Trees ever look the same, and that’s exactly the magic.
"Such a beautiful piece! Quality is exceptional. Very easy to apply and looks painted on the wall. My toddler loves pointing at the birds on the tree. Thank you for creating such beautiful work!"
Ana ~ Miami, FL
Large Village Kit
We’ve always been a little head over heels for this Large Village Kit from the Rooftop Collection... and it turns out you are too. Inspired by real houses Julianna fell in love with while visiting Anton’s family in Copenhagen, these storybook buildings were made to create a statement wall (or two… or three). We absolutely love seeing the many ways families bring these villages to life.

MORE POPULAR NURSERY AND KIDS ROOM DESIGNS OF 2025
Here are more top choices families returned to again and again this year, each one unique and finding its place based on the room, the light, and the little person who lived there.
Medium Suns and Mini Suns
All of our suns are perennial favorites because who doesn't love waking up to happy sunshine? Both medium and minis made the list this year, but we also offer large and extra large for those who want to soak up a little extra glow.
Feathered Friends and dino buddies
The Birds on a Wire Kit ... A longtime favorite for a reason. These little birds feel simple at first glance, but families love how much personality they bring to a room. Easy to arrange, easy to rearrange, and always ready to tell a quiet story along the wall.
The Dino Kit Proof that dinosaurs can be playful and beautifully designed. This kit has been a go-to for kids who love everything dino, and for parents who want something imaginative without overpowering the space.
Rainbow style
Rainbow Hearts Soft, colorful, and full of feeling. These hearts have shown up in nurseries, playrooms, and cozy corners again and again, adding just the right touch of warmth and love wherever they land.
Rainbow Uppercase Alphabet Learning meets art in the most joyful way. Families return to this one for rooms that grow with their kids — playful for early years, meaningful as letters turn into names, words, and stories.
Watercolor Waves from the Sag Harbor collection
This was the design families chose when they wanted a room to feel peaceful from the very first day. Inspired by quiet mornings near the water, these soft watercolor waves bring a sense of calm that works just as beautifully in a baby’s nursery as it does in a grown-up space meant to slow things down.
"Looks even better than I’d hoped. I wasn’t in the mood to paint or wallpaper, but this room needed a cute wall. These decals were so easy to put up and reposition. I put them up with my daughter so there was lots of repositioning going on and she loved being able to help."

Seeing this year’s most-loved designs come together has been such a joy for us. We love seeing how you make these designs your own. And if you’re new to Mej Mej, our reviews page is full of photos from families around the world. Real rooms, for real kids, and so much imagination.
As we look back on 2025, we’re incredibly grateful to have played even a small part in the homes you created for your children. Thank you for supporting our small family business and making this our best year yet.
We hope these favorites of the year spark ideas for what you're planning next, and we can’t wait to see what you bring to life in 2026.
Wishing you a very happy new year filled with creativity, joy, and wonder. (And maybe a few naps!)
