A DIY geometric wedding ceremony backdrop made of wooden triangle shelves will give a modern edge to your nuptials. Here I kept the wood its natural blonde color, although you could paint or stain it to perfectly match your wedding colors. The flowers could also be customized to coordinate with your bouquet and centerpieces. A few materials and a few hours are all you need to create this show-stopping installation.

Lay out your triangles on the floor in sections, I used 30 wood triangles to create this look. Start gluing them together, I used wood glue. Use clamps to hold the triangles together while the glue dries.

Stand the backdrop against a wall. Continue to glue and clamp the triangles to create height and width for your backdrop. Follow the manufacturer's instructions for the glue. I let my clamps each set for about 20 - 30 minutes before I unclamped them. If you will be transporting this in a car, I recommend putting it together in smaller, more manageable sections instead of gluing the entire thing together. Then onsite, you can glue all the sections together.

Remove all of the clamps when the glue is dry.

Time to add the flowers! Zip tie pre-soaked floral foam to the side of a triangle. Add in large focal flowers first, like big lavender roses. Next, fill in the gaps with a pretty greenery filler and add small flowers as accents. Repeat this process where ever you'd like to add florals to your backdrop. You could also use faux flowers and greenery like, these peony stems, caledonia magnolia or silver dollar eucalyptus. I also added pillar candles around the backdrop.
