How to Make the 3D Popcorn
The popcorn is what makes this bulletin board so unique!
Step 1: Spray the Foam
Lay out sheets of wax paper or parchment paper on a protected work surface.
Wearing gloves, spray small mounds of expanding foam. Don’t worry about making them perfect—the foam naturally expands into fun, popcorn-like shapes. I tried to do one big blog and a squiggle along the bottom.
Create several different sizes for a realistic look.
Allow the foam to cure completely according to the manufacturer’s instructions, usually overnight.
Step 2: Trim if Needed
Once the foam has hardened, use scissors or a craft knife to trim away any pieces that don’t resemble popcorn.
Each piece will be unique—that’s part of the charm!
Step 3: Paint the Popcorn
Once dry, lightly dry brush soft yellow paint onto the raised areas.
If you’d like extra dimension, add just a tiny touch of tan to some creases.
This creates the buttery popcorn appearance without looking too dark.
Step 4: Make Popcorn Kernels
Cut out the popcorn kernals (PRINTABLE HERE)
Scatter these around the bulletin board to tie the theme together.
Create the Background
Cover the bulletin board with red striped paper to resemble a popcorn box.
I orginally found a striped tablecloth but ended up swapping it out for this striped wrapping paper because I was nervous the white words would get lost on the white stripes of the tablecloth.
For extra visual interest, add a fun black swirl border around the outside.
The bold colors help the white popcorn stand out.
Add the Title
Use large black letters to spell:
POPCORN
Keeping the title simple allows the inspirational message to become the focal point.
Add the Growth Mindset Quote
Print each phrase. I didn’t want to have to write each word, or try to find letters so I just created a printable. (GET THE PRINTABLE HERE)
Cut them apart and arrange them in a playful layout across the center of the board.
This creates movement and makes the message easy to read.
The quote reads:
Popcorn is popped in the same pan, same heat, same oil… but they don’t all pop together. Don’t compare yourself to anyone else. We all pop at different times.
It’s a wonderful conversation starter during the first weeks of school.
Attach the Popcorn
Once everything else is finished, hot glue or securely attach the foam popcorn around the edges of the bulletin board. I hold them into place until the glue is dry.
Mix large and small pieces to create balance.
Allow some popcorn to overlap the border for an even more dramatic 3D effect.
Why This Message Matters
The beginning of a new school year can be challenging for students.
Some children learn to read quickly.
Others need more time.
Some make friends immediately.
Others are naturally shy.
This bulletin board reminds students that growth doesn’t happen on the same timeline for everyone.
It’s a powerful visual that encourages patience, confidence, and perseverance.

Frequently Asked Questions
Can I make this without expanding foam?
Yes! You can create popcorn from crumpled tissue paper, cotton batting, or paper mâché, but expanding foam gives the most realistic, three-dimensional effect.
Is expanding foam lightweight?
Yes. Once cured, the foam is surprisingly lightweight, making it easy to attach to bulletin boards.
Can I reuse the popcorn?
Absolutely! Store the foam popcorn in a large plastic bin after the school year ends. Since it’s durable and lightweight, you can reuse it year after year.
