Materials You’ll Need for the Christmas Tree
- Clean mussel shells
- Styrofoam cone or sturdy paper cone
- Hot glue gun and glue sticks
- Starfish (Store bought or DIY it)
- Acrylic Paint (black or dark blue)
Step 1: Clean the Mussel Shells
Wash the shells thoroughly using warm water and dish soap.
If needed:
- Soak them in a solution of water and vinegar for 20–30 minutes.
- Scrub away any dirt or residue.
- Allow them to dry completely before gluing.
💡Tip: Save shells throughout the year so you’ll have plenty when Christmas arrives.
Step 2: Prepare the Cone
Paint the foam cone a dark gray or black color.
Although most of the cone will be covered, painting it helps hide any small gaps between shells.
Allow the paint to dry.
Step 3: Glue the Mussel Shells
Start from the bottom.
Glue each shell with the pointed end facing upward and overlap the rows like roof shingles.
Continue working upward around the cone.
Each new row should slightly overlap the previous one to create a full, layered appearance.
As you reach the top, use smaller shells for a cleaner finish.
Step 5: Attach the Starfish
Glue the starfish securely to the top of the tree.
Hold it in place until the glue cools completely.
Styling Ideas
This DIY tree pairs beautifully with:
- White ceramic houses Driftwood accents

Create a small coastal Christmas village by displaying multiple trees in different heights.
Tips for the Best Results
- Sort shells by size before gluing.
- Use smaller shells toward the top.
- Overlap shells generously for a fuller tree.
- Work in small sections so the glue doesn’t cool too quickly.
- Seal both the shells and clay starfish if displaying year after year.
