As a family we love walking along the coastline hunting for beach glass, often having a competition to see who can find the smallest piece, or the largest or even a blue piece (particularly rare where we live). There’s nothing like a walk scouring the beach for treasures.

But as always, there is a dilemma once home about how to display the beach glass. Let me show you how to create your own sea glass Christmas tree at home.

Where to find sea glass

Sea glass is a type of beach and ocean debris that has been washed up on the shore. It can be found in many different colors, shapes, sizes, and textures. The most common color is blue, but it can also come in other colors such as green or white. Some sea glass pieces are smooth while others have sharp edges.

Variations to the beach glass Christmas trees

With my three trees I have demonstrated choosing one solid color for your trees, such as green, but also an ombre effect where you start with one color and gradually change colors as the tree progresses. To change them up you could add a starfish to the top to represent a star – I have chosen not to do this as I wish to display my Sea Glass Trees all year round!

Applying sea glass

We are going to start at the base of the cone, applying a row of seaglass around the base with a dab of glue per piece of natural glass from the glue gun.

Ensure your remove loose glue strands as you work (they are the downside to glue guns!).

Preparing the base and trunk

My husband kindly sliced me three bases from a piece of yew he had in the shed (using a band saw), a great alternative is to buy some ready-made log slices or even drinks coasters. If you are making your own apply olive oil with a cotton rag to bring out the color of the wood.

Cut a piece for the tree trunk, ours is approx in length. Ensure you have good flat ends which are 90 degrees to the trunk piece – if your angle is off your tree will tilt slightly!!

Finishing the Sea Glass Christmas Tree

Now to assemble the finished beach glass Christmas trees, my favorite bit! Using your hot glue gun attach the tree trunk to your wooden base.

Lastly, apply glue to the top of the trunk and place your tree ornament centrally into the trunk. Step back and admire your handwork.

    A very creative idea! A 'Reduce, Reuse, Recycle' idea too. It helps clean up the beach and becomes a beautiful accent piece. Lovely!
