12 DIY Galaxy Decor Ideas That Look Way More Expensive Than They Are

You don’t need a big budget to bring the cosmos into your home. With a few craft supplies, some acrylic paint, and basic techniques, you can transform dressers, jars, canvases, and lampshades into stunning galaxy-inspired pieces. The right color palette and finishing touches make all the difference. Twelve ideas ahead will show you exactly how it’s done.

Galaxy-Paint a Dresser or Side Table for Under $15

Transforming a worn dresser or side table into a galaxy-themed showpiece costs less than $15 when you use the right materials and technique. You’ll need black, navy, purple, and white acrylic paint, plus a sea sponge. Apply dark base coats first, then layer lighter colors using a dabbing motion. Finish with white speckling to mimic stars.

Make a Nebula Jar With $5 in Craft Supplies

A nebula jar captures the swirling colors of deep space inside a simple glass container, and you can build one for around $5. You’ll need cotton balls, acrylic paint, glitter, and a mason jar. Layer cotton, paint, and glitter repeatedly until the jar fills up.

Each layer creates depth, mimicking a real nebula’s luminous, cloud-like structure.

Create Galaxy Wall Art With Sponges and Acrylic Paint

Galaxy wall art doesn’t require special skills or expensive equipment, and a few sponges with acrylic paint can produce stunning results. Dab deep navy and black paint onto your canvas first, building your base layer. Then apply purple, blue, and white in irregular blotches, blending edges softly. Finish by flicking white paint for star effects.

Turn Old Canvases Into Deep-Space Galaxy Paintings

Old canvases you’ve stored away are perfect starting points for deep-space galaxy paintings, since their pre-primed surfaces accept acrylic paint easily. Apply a black base coat first, then layer deep blues, purples, and whites using a dry-brush technique. Add small white dots for stars using a detail brush. You’ll transform forgotten canvases into striking, gallery-worthy wall art.

Sew Galaxy Throw Pillows in a Single Afternoon

Throw pillows are one of the fastest ways to bring galaxy-themed decor into your living room without committing to large-scale changes. Choose deep navy, violet, and black fleece fabrics, then cut two matching squares. Sew three sides, stuff firmly, and close the final seam. Add star-shaped fabric paint details before finishing. You’ll complete several pillows in one afternoon.

Galaxy-Dye Your Curtains and Fabric Décor at Home

Transforming plain curtains into cosmic statement pieces is easier than you might think, and you don’t need professional dyeing experience to pull it off. Use navy, black, and purple fiber-reactive dyes on white cotton or linen fabric. Scrunch sections tightly, apply colors in layers, and mist with water to encourage organic bleeding. Seal with a fabric fixative once dry.

Paint Your Bedroom Ceiling Into a Galaxy for Under $30

A galaxy ceiling can completely change the atmosphere of your bedroom without requiring a large budget or professional help.

Using black, navy, and purple craft paint, you’ll sponge on layers of color, then flick white paint for stars.

A small can of glow-in-the-dark paint adds depth, keeping your total cost well under $30.

Make a Glow-in-the-Dark Galaxy Star Map for Any Room

Why stop at the ceiling when you can bring a personalized star map to any wall in your home? Choose a significant date, then use a free star map generator to print your custom constellation layout. Trace it onto black canvas using glow-in-the-dark paint, adding depth with navy and purple tones. Mount it above a headboard or desk for maximum visual impact.

Build a Galaxy Shadow Box Wall Display for Under $20

Star maps are a fantastic way to personalize your space, but shadow boxes let you build something even more dimensional and tactile. Grab a deep-frame shadow box, black velvet fabric, and metallic paint. Layer painted cork stars, iridescent beads, and LED fairy lights inside. You’ll create stunning depth and texture for under $20.

Turn Old Glass Bottles Into Glowing Galaxy Accents

Those old wine bottles or mason jars sitting in your recycling bin can become striking galaxy-themed accent pieces with just a few supplies.

Apply rubbing alcohol inside, then swirl in acrylic paints like deep navy, violet, and black.

Add iridescent glitter, and insert a battery-powered fairy light strand.

The light diffuses beautifully through the painted glass, creating a luminous, nebula-like glow.

Make Galaxy Resin Coasters That Look Professionally Crafted

Resin coasters are one of the most rewarding DIY projects you can tackle, and the galaxy aesthetic translates beautifully into this medium.

Pour clear epoxy resin into circular molds, then swirl in deep navy, purple, and black pigments.

Add silver mica powder for star-like shimmer.

Let it cure fully before removing it from the mold.

Create a Galaxy Lampshade That Casts Dreamy Starry Light

Transforming a plain lampshade into a galaxy-inspired piece lets you add ambient, atmospheric lighting to any room. Paint the interior with deep navy or black acrylic, then layer on purples and blues using a sponge. Add white dots for stars, and finish with a light iridescent glaze. When lit, the shade casts soft, diffused color across surrounding walls beautifully.

Picking the Right Color Palette

Choosing the right color palette is where your galaxy project truly comes together, and it’s easier than you might think. Stick to deep navy, violet, and black as your base colors. Then layer in magenta, teal, and electric blue for depth. Add white and silver for star accents. These hues create authentic cosmic contrast without overwhelming your space.

Common Mistakes

With your color palette locked in, you’re ready to start creating, but a few common mistakes can quickly derail even the most carefully planned galaxy project.

Don’t skip the black base coat, since it anchors your colors and creates depth.

Avoid overblending your purples and blues, because muddy transition(s) flatten the design.

Work in thin, deliberate layers instead.

Final thoughts

You now have everything you need to transform ordinary objects into galaxy-inspired pieces that look far more expensive than they are. Start with one project, whether it’s a nebula jar or a painted dresser, and build your confidence from there. Stick to deep navies, purples, and teals, seal your finished surfaces, and you’ll create cohesive, polished results throughout your space.
