DIY Geometric Christmas Trees

989

The holiday season is around the corner and one of the best parts for me is the tree!! But not everyone has space for a real thing or the time to pack away all those decorations when January rolls around. Ermmmm, that would be me 😉 These unusual, geometric Christmas trees are quick and easy to make and you can personalize them to fit your unique style. It doesn’t matter if it’s rustic and natural or modern glam, the trees look lovely and they’re budget-friendly too.

What You Need to Make Geometric Christmas Trees

To make these super easy trees you only need a few basic things:

• Plaster of Paris
• Flexible chopping mat
• Twigs or small branches

You’ll also need sticky tape, a pair of scissors, a pen, paper, a small mixing container, and a tall glass.

Making The Mold For The Geometric Christmas Trees

Start by drawing an isosceles triangle to use as a template. The size of the triangle will determine how high and wide your geometric trees will be. Our trees are roughly 14 cm (5.5″) high and 7 cm (2.75″) wide at the base.  Use the template to cut 4 triangles from the flexible chopping mat. If you can’t find one of those mats, you can cut the template from cardboard too. Just make sure to cover it with sticky tape so it’s waterproof.

Lay the pieces side by side in the shape of a fan and tape them together along the sides. Fold the fan shape to form a triangular pyramid, aka tetrahedron. Try saying that one out loud, it’s such a cool word.

Okay, I’ll stop now 😀 Tape the overlapping triangles down.

Now, grab that glass and place the triangular pyramid mold thingy inside, with the point facing down and the opening at the top. If the mold wobbles around inside the glass you can add some soil or dry beans to stabilize it.

Cut a square from the cutting mat and make a hole in the middle. We’ll be using that little square in a minute to keep the “trunk” of the Christmas tree in place 😉

Making the Geometric Christmas Trees

Mix up equal quantities of plaster of Paris and water to form a smooth, runny paste. Pour or spoon the mixture into the mold. Give it a shake to get rid of any air bubbles. Push a small branch or twig into the hole you made earlier and place it on top of the mold. Just make sure that there’s a long enough piece of the branch inside the plaster of Paris mix.

Let the plaster of Paris dry completely, about 10 minutes, before removing the mold.

For the base of the tree, you can either make a simple little bucket mold using this template or you buy a small galvanized bucket online. Just fill the bucket with plaster of Paris and plant your geometric tree 😉

Once the base has set your Christmas trees are ready to be decorated.

2 Ways to Decorate The Geometric Christmas Trees

For this post, I wanted to show you two possible ways to decorate the little trees. They’re both really easy to do, but feel free to experiment and do your own thing.

Option 1 – Rustic Goodness

First up, a little rustic goodness that fits right in with the whole farmhouse look.

Tie a few pretty beads onto a piece of twine and simply drape them on the Christmas trees. If you want to use the trees as part of your table decor you could make name tags for each of your guests and tie them on instead. Combining the beads and tags would look lovely too.

Don’t forget to pin it for later if you like the rustic look.

Option 2 – Modern Glam

If modern and glamorous is more your style then the unique shape of the geometric Christmas trees is the perfect starting point to create something that’s both chic and classy.

All you need for this look is some tacky glue, a paintbrush, and copper leaf. I love this stuff. A little goes a long way. This booklet of 10 sheets has been used to upcycle old, unusable paintbrushes and  I even used some of the leaves to “paint” the most beautiful wings for the angel portrait in our small metallic bathroom

Paint the tacky glue onto the tip of the trees and around the base and then gently brush on the copper leaf.

Place the Christmas trees on a pretty plate, add a few fairy lights and enjoy.

If you like the modern glam look don’t forget to pin this version.

These geometric trees can be used wherever you want to add a little budget-friendly Christmas magic. Put them in your window sill or on the mantle. Or use them as part of your table decor. The possibilities are endless. So tell me where would you put them?
