How to Make a Decorative Mirror Frame Using Cardboard

Looking for an inexpensive and eco-friendly way to upgrade your mirror? Try making a decorative mirror frame using cardboard — it’s creative, simple, and perfect for anyone who loves DIY projects with a personal touch.

Cardboard is often overlooked as a crafting material, but it’s strong, lightweight, and incredibly versatile. Best of all, it’s usually free — you can reuse boxes from online orders or grocery deliveries, giving new life to something that would otherwise be thrown away.

This project takes just a few hours and requires only basic tools. Whether you’re redecorating your home or looking for a gift idea, this tutorial will show you how to create a stylish, handmade frame that makes any mirror feel like a custom piece.

What You’ll Need

Before starting your cardboard mirror frame, gather the following supplies:

Item	Description
Sturdy cardboard	From shipping or packaging boxes
Ruler & pencil	For accurate measuring and marking
Craft knife or box cutter	To cut the cardboard precisely
Glue or Mod Podge	Strong adhesive for layering
Scissors	For trimming smaller pieces
Sandpaper (optional)	Smooth rough edges
Paint, wrapping paper, fabric, or wallpaper	For decoration
Clear varnish or sealant (optional)	Protects the finished frame

Most of these items are likely already in your home, making this one of the most affordable decor DIYs around.

Step 1: Measure Your Mirror

Begin by measuring the width and height of your mirror. This will determine the size of your cardboard frame.

Add about 2 inches (5 cm) to each side — this gives you a frame thickness that looks balanced without overwhelming the mirror.

Use a ruler and pencil to mark the dimensions on the cardboard. Then carefully cut out two rectangles:

• One for the front face
• One for the back support

You’ll also need strips of cardboard for the frame sides , based on the desired thickness of your border.

Step 2: Cut the Frame Pieces

Now it’s time to build the structure of your frame.

Cut four long strips of cardboard — these will form the sides of the frame. The width of each strip depends on how thick you want the frame to appear. A good starting point is 2 inches (5 cm) wide.

Assemble the pieces by gluing the side strips between the front and back cardboard panels. Use strong glue and hold the pieces together until they set.

Tip: If your mirror has rounded corners, trace them onto the cardboard before cutting for a cleaner fit.

Step 3: Fit the Mirror into the Frame

Once the frame is assembled, cut out the center to create the opening for your mirror.

Trace the mirror’s exact shape onto the front panel, then carefully cut it out using a craft knife. Test the fit by inserting the mirror — it should sit snugly without wobbling.

If needed, add small cardboard spacers inside the opening to secure the mirror in place.

Pro tip: For extra safety, you can glue the mirror to the back panel using hot glue or silicone adhesive — just make sure it’s fully dry before handling.

Step 4: Decorate the Frame

Now comes the fun part — decorating your cardboard mirror frame . Since cardboard is easy to paint and cover, the possibilities are endless.

Here are some ideas:

• Paint the frame in bold colors or soft pastels
• Wrap it in patterned paper, gift wrap, or wallpaper
• Cover it with fabric using decoupage glue
• Add texture with yarn, buttons, beads, or pressed flowers
• Glue on decorative trims , lace, or even recycled materials like bottle caps

Use your imagination and match the style to your room’s decor — whether it’s modern, rustic, boho, or minimalist.

Remember: if you use paper or fabric, finish with a coat of clear varnish or Mod Podge to protect your design and give it a polished look.

Step 5: Paint or Seal the Frame

After decorating, apply a final protective layer to make your frame more durable.

Use acrylic sealer, spray varnish, or brush-on polyurethane to keep your decorations intact and prevent peeling or fading over time.

If you painted your frame, consider adding a second coat for richer color and even coverage. Let each coat dry completely before applying the next.

This step ensures your frame lasts longer and keeps its fresh look, even with regular cleaning or movement.

Tips for a Professional Finish

Even though this is a beginner-friendly project, a few small touches can elevate the final result:

• Sand rough edges lightly for smoother surfaces.
• Use clamps or heavy books to press glued layers while drying.
• Line up seams neatly when covering with paper or fabric.
• Paint corners separately before assembly for cleaner lines.

These finishing details help your frame look store-bought — not homemade.
