One simple purchase often turns into a pile of metal discs: bottle caps. Instead of tossing them, you can transform these small scraps into a striking wall mirror that reads like reclaimed art. With modest tools, some patterned paper, and a little patience, this project produces a dramatic sunburst-style piece that’s both eco-friendly and easy to personalize.

Bottle caps bring a mix of color, texture, and circular geometry that makes them ideal for radial designs. They are light, plentiful, and can be altered with paint or paper. For homeowners who enjoy upcycling, this craft keeps items out of the trash while delivering a conversation-starting focal point.
Tools and supplies to collect before you begin
- Lots of bottle caps — dozens are needed for a full border.
- Decoupage glue (for example, Mod Podge) or all-purpose craft glue.
- Patterned napkins, wrapping paper, or thin scrapbook paper for decoration.
- Acrylic paints and a small paintbrush for edges and accents.
- Hot glue gun and extra sticks for fast bonding.
- Large cardboard or foam board to build the backing.
- A round mirror — 8–12 inches works well; thrift stores and dollar shops are good sources.
- Scissors, craft knife, ruler, and a pencil.
- A picture hanger or adhesive hook to mount the finished piece.
Preparing caps: cleaning, shaping, and decorating
- Wash each cap with soap and water. Let them dry completely.
- If you plan to decoupage, separate the patterned layer of a napkin. Use only the top printed ply.
- Cut paper squares slightly larger than each cap.
- Brush glue onto the cap face, press a paper square on top, and smooth out wrinkles.
- Seal the paper with another thin layer of glue. Fold excess paper under the rim and secure it with glue.
- Paint the sides of each cap with acrylic paint to hide rough edges and create uniformity.
Tip: If you prefer simpler steps, skip decoupage and paint the caps in a palette that matches your room.
Constructing the mirror’s layered frame
Cutting and assembling the backing
Trace your mirror on the cardboard and cut out a circle the same size. Then cut a second cardboard circle a few inches larger. Glue the smaller circle centered onto the larger one to create a raised mount.
Attaching caps in concentric rings
- Arrange caps on the larger disc to plan three concentric rings: inner, middle, and outer.
- Glue the first ring of caps around the inner circle. Leave small gaps if you want a lace-like effect.
- Build the second ring by fastening caps so their edges meet the first ring. Use hot glue for a secure bond.
- Create a third ring for a full sunburst look, staggering caps where needed for visual depth.
- Once the caps are set, center the mirror on the raised cardboard disc and fix it with hot glue.
Secure tip: Press each cap firmly while the glue cools so the bond is tight and even.
Style variations and customization ideas
- Choose a coastal theme with sea-patterned napkins and aquamarine paint.
- Use metallic paint for a glamorous, vintage look.
- Fill visible gaps with beads, faux pearls, or small gemstones for sparkle.
- Mix caps of different sizes or add short wooden dowels for a spiked effect.
Hanging the finished piece and practical care
Attach a sturdy hanger to the cardboard backing or use two adhesive hooks for balance. Hang the mirror on a wall that receives some indirect light to highlight the textured border. To clean, dust gently and avoid soaking the decoupage areas. If any caps loosen over time, reapply hot glue to reinforce them.
