DIY: Modern Geometric Backdrop

With a few everyday tools, transform plain white poster board into a chic geometric backdrop perfect for a modern-themed wedding.




  • desktop printer
  • This template
  • 4 sheets of 8.5"x11" cardstock
  • 9 sheets of 28"x22" white poster board 
  • scissors
  • x-acto knife
  • yard stick or measuring tape
  • self-healing cutting mat
  • double-sided tape
  • duct tape
  • fishing line (to hang backdrop)

Steps One - Three:
1. Download and print all four pages of template onto an 8.5" x 11" sheet of cardstock. Cut out shapes and tape pieces together to form a star. This is your template for tracing. 
2. Trace template onto the back (dull side) of a sheet of poster board. On a 28"x22" sheet, you can fit three stars. 
3. Cut out star shapes. From beginning to end, each star takes about five minutes. The backdrop I created measures 44"x 53" and is made up of 27 star shapes.
Step Four: 
Stack the stars together, orienting them so the edges are even.
Step Five:
Working from left to right, lay out a row of stars, overlapping the "arms" of each piece. Use double-sided tape to affix edges together. Important: The center line of each star must be exactly vertical and parallel to each other. Keep each row perfectly straight and make sure each star piece is oriented the same direction so the pieces fit together consistently. This is to ensure you have a uniform, symmetrical backdrop. I used the slats of my floor as a guide to line up my stars, but you can also use a measuring tape or yardstick. My completed first row is five stars across.
Step Six:
Lay out the second row of stars. Starting on the left, place a star so that the center line meets where the two bottom stars join. Complete the row for a total of four stars. Check that the center line of each star is perfectly vertical across all rows. You can use your yardstick or measuring tape for this.

Steps Seven - Nine:
7. Repeat the process for a third row with five stars across. Then a fourth row with four stars across. Continue for a total of 6 rows.
8. Carefully flip the backdrop over and use small pieces of duct or masking tape to reinforce the "joints" where the stars meet.
9. Trim off the edges on the left, right, and bottom.
Step Ten: 
To finish the top of the backdrop, trim off star pieces as indicated in picture. You will end up with three "points" along the top.
Step Eleven: 
On the backside of the finished three points, attach a small piece of duct tape a couple inches wide. Punch out a hole using a small hole punch. To hang, string fishing line through the holes, knot, and attach to ceiling hooks.
