Seashell Ornaments DIY: 11 Easy Coastal Christmas Craft Ideas

Hey there, fellow shell-lover! Ever find yourself with a bag full of beautiful shells after a beach day and wonder, what now? If you’ve been thinking about turning those ocean treasures into something special, you’re in the right place.

In this post, we’re diving into fun, easy, and creative ways to make seashell ornaments DIY, perfect for coastal vibes, holidays, gifts, or just as keepsakes. I’m super pumped to share what’s worked for me (and what you’ll totally enjoy doing too).

Growing up, I used to bring home “just one more shell” every time I hit the beach. After a while, my shelf looked like a mini ocean museum. 😄 One Christmas, I glued a few shells onto a small tree, and boom!, instant coastal charm. That’s what sparked my love for seashell ornaments DIY coastal Christmas projects. Since then, I’ve experimented with all sorts of designs, so I can’t wait to walk you through them.

Why Seashell Ornaments? (And Why You’ll Love DIY)

The charm of making your own décor

• Unique & personal: No two shells are the same. When you craft your own ornaments, each piece becomes a one-of-a-kind memory from the beach.
• Budget-friendly: You don’t need fancy supplies. Most times a bit of glue, paint, string, and your shell stash is enough.
• Kid-friendly & family fun: It’s a great activity with kids (hello seashell ornaments DIY kids!), holiday seasons, or lazy beach-house weekends.
• Eco-mindful: Instead of shelling out for store-bought decorations (often plastic or mass-produced), you’re re-using natural finds, sustainable and meaningful.

Honestly, I think seashell crafts (yes, shell ornaments DIY seashell crafts) have this cozy, nostalgic vibe that no store-bought ornament can match.

How to Get Started Seashell Ornaments DIY ?: Prep & Basics

What you’ll need (starter supplies)

Here’s a quick checklist before you begin:

• Clean, dry seashells (clams, scallops, cowries, any shape you like)
• Strong adhesive or hot glue gun (for sturdier pieces)
• String, ribbon, twine, or fishing line (for hanging)
• Optional: acrylic paints, glitter, gold/silver leaf, varnish, for decoration
• Optional: small beads, driftwood pieces, hooks, for extra flair

Cleaning and preparing shells

Before gluing or painting, make sure your shells are clean and free from sand or salt residue. A simple rinse and dry under the sun works. This step ensures your ornament lasts longer (less chance of glue peeling or paint flaking).
