DIY seaglass Christmas tree

Hi friends! We’re excited to share this beach-inspired DIY sea glass Christmas tree craft using your sea glass collection that you’ll want to display every holiday season.

A simple and elegant DIY Sea Glass Christmas Tree

Collecting sea glass with the kids is one of our favorite things to do when we’re at the cottage. Technically, it’s called beach glass since we’re at the lake (and not the sea) but we’ve gotten accustomed to saying sea glass over the years. Each of the kids takes a little baggie with them to hold all their finds until they can sort them by color when they return home. We could undoubtedly walk for hours combing the beach for treasures.

We normally share DIY tutorials for making driftwood crafts such as our driftwood crab wall art, concrete and driftwood sailboat decor, driftwood reindeer ornaments and large driftwood Christmas tree so we were excited to share this simple sea glass craft for a change. If you don’t have enough sea glass in your collection, it can also be purchased at a local nursery or craft store.

We love the way these sea glass Christmas trees turned out. They are cute and fun with the starfish topper but also elegant with all the natural glass. For other ways to use your sea glass collection, consider making a pretty macrame seaglass necklace or seaglass planter or even simply add them loosely in a beach-themed terrarium.

Supplies needed to make a sea glass Christmas tree

How to make a DIY Sea Glass Christmas Tree:

Preparing the Cones:

Poke a hole through the top of the cone using a sharp-pointed tool such as an awl or a wooden skewer. The toothpick is likely not strong enough to break through the paper mache.

  • DIY seaglass Christmas tree

To alter the size of the cones so the trees are at differing heights, simply cut off some of the height at the bottom of one of the cones. Wrap a piece of scotch tape approximately ¾” from the base. Using a utility knife or a good pair of scissors, cut along the taped edge to reduce the height of the cone. Remove the tape before moving on.

  • DIY Seaglass Christmas tree

Next, paint the cones and toothpicks using acrylic paint in white. Leave the paint to dry fully before moving on to the next step.

Preparing the Star Topper:

Turn the starfish embellishments with the backside facing up.
Apply a dab of glue to the backside of the starfish and place one of the painted toothpicks down on top so one end hangs past the starfish. Hold the toothpick in place until the glue sets. Put aside for the time being.

  • DIY seaglass Christmas tree

Applying the Sea Glass:

If you’re using actual sea glass collected at the beach, be sure to thoroughly wash and dry it before gluing.
Preheat the hot glue gun and remember to work quickly as the glue from the glue gun sets quickly but work carefully to avoid injury from the hot glue.

For this first Christmas tree, we used only green glass. Starting at the base of the cone, apply a dab of glue as shown and press one piece of sea glass over the glue. Don’t extend the sea glass past the base of the cone. Continue around the rim of the cone gluing one piece of glass at a time.

For the second row, overlap the bottom edge of the pieces with the top each of the sea glass from the previous row.

Continue working one sea glass at a time and one row at a time.

Work your way up to the top of the cone, using different sizes and colors.

At the top, avoid covering the hole you made earlier with glue or glass. 

adding hot glue to the tip of the cones

For our second Christmas tree, we used a mix of white, green and blue glass but you can use any combination of sea glass you like.

Finishing the Sea Glass Christmas Tree:

Once the glue has fully set, clean off any loose glue strands. Lastly, place the star on the top of each tree by inserting the end of the toothpick into the hole at the top of the cone.

Speaking of Christmas trees, we have another adorable tree craft we think you’d love. These Wood Slice Trees are super easy to make using foam cones and rustic wood slices! 

Lastly, for those of you with a coastal themed home, this Coastal Branch Tree for Christmas is the perfect addition to your beach themed holiday decor!

    Do you bake it after or use a hairdryer?

      There’s no need to bake or use a dryer as hot glue sets within seconds :)

    Why can’t or can a foam cone be used instead of cardboard?

      Yes you can use foam. However, when using hot glue on foam it can melt the foam and make it more difficult to adhere the glass.

    I work with first grader and using a glue gun would be dangerous and impossible with 23 kids. Do you think tacky glue would work just as well.

      I don’t think it will. You could try a low temp glue gun, or try one of our kid’s crafts instead! :) https://craftsbyamanda.com/category/craft-tutorials/kids-crafts-2/
