This project is proof that holiday magic can spring from the simplest materials.

Bolts, nuts, and marbles become a modern tree, combining raw strength with playful sparkle.

It’s the perfect project for anyone who loves reusing odds and ends in a creative way.

Once assembled, the tree becomes more than a decoration, it’s a conversation piece that blends craftiness with craftsmanship.

Materials Needed

• 15-18 hex nuts (1” size recommended for main body)
• 6-8 smaller hex nuts (½” size for base)
• 1 large bolt (3” long, ½” diameter for trunk)
• Strong epoxy or hot glue (industrial strength preferred)
• 15-18 marbles (standard 16mm diameter, assorted colors)
• 1 piece of craft wire (12-14 gauge, about 6” long)
• Metallic spray paint (optional, silver or gold finish)

Step-by-step Guide

Step 1: Arrange 6-8 smaller nuts in a circle to form the tree’s base, then glue them securely together.

Step 2: Attach the large bolt vertically to the base, this will serve as the trunk.

Step 3: Begin stacking the larger 1” nuts in a triangular pattern up the bolt, layering them to mimic a tree shape.

Step 4: Place marbles inside each nut, securing them with epoxy or hot glue so they stay in place.

Step 5: Bend your craft wire into the shape of a star and attach it to the top nut as a tree topper.

Step 6: (Optional) Spray-paint the nuts and bolt for a more polished finish, or leave them raw for a rugged industrial style.

Tips:

Use marbles in classic holiday shades like green, red, and blue for a festive feel.

If you want extra sparkle, dust the base with glitter before sealing everything.
