Dotted Half Moons

Theresa Brandon and Nate Parker from Willow Creek Huntley in Huntley, IL brings us these styrofoam cup dotted half moons.

This design is a variation of Big Baller, and was designed by Nathan Parker, Technical director for Willow Creek Huntley, and Theresa Brandon. The background for each piece was 4′ x 8′ foam, painted black. Each piece had about 100 foam cups glued in concentric circles using 4 or 5 dots of low temp hot glue on each cup. (8 ounce cups from Uline.com, 1000 for $34). They would mark out the baseline and the outer circle and then eyeball the layout of the rest of the cups. The first one they did took the longest to layout, but it got easier and faster as they did more panels. They would get up on a ladder to look down at the panels to make sure the layout was fine before they would glue them into place.

Creating Dimensional Texture with Everyday Materials

The genius of this dotted half moons design lies in its transformation of ordinary styrofoam cups into extraordinary visual texture. By arranging the cups in concentric circles on a black foam background, the team at Willow Creek Huntley created a sculptural backdrop that catches light in fascinating ways. The curved surfaces of the cups create subtle shadows and highlights that shift throughout the service as stage lighting changes, adding movement and depth to the stage without any electronic components or moving parts.

This approach exemplifies how churches can achieve professional-looking stage designs on modest budgets. At roughly $34 for 1000 cups plus the cost of foam boards and glue, the entire project likely came in under $100—a fraction of what custom fabricated stage elements would cost. The design demonstrates that creativity and careful execution often trump expensive materials when it comes to creating visual impact.

The half-moon shape carries symbolic significance in worship contexts, suggesting phases, cycles, and the passage of time. When multiplied across several panels and arranged on stage, these forms create a rhythmic pattern that draws the eye without overwhelming the space. The dotted texture created by the cup bottoms adds another layer of visual interest, creating a pointillism effect that reads differently depending on viewing distance.

Construction Techniques for Foam Cup Designs

The construction method used here—low temperature hot glue applied in small dots—provides strong adhesion without damaging the foam cups or backing boards. Low temp glue is essential for this application, as high temperature glue can melt through styrofoam and create messy, uneven attachment points. The technique of using 4-5 small dots per cup rather than a continuous bead allows for some flexibility and reduces the amount of glue needed while still providing secure attachment.

Creating the concentric circle pattern requires careful planning but becomes faster with practice. The Willow Creek team found that marking baseline and outer circle guides, then eyeballing the intermediate placement, struck the right balance between precision and efficiency. Getting above the panels on a ladder to check the layout before gluing is a pro tip that prevents costly mistakes—what looks correct at eye level may appear quite different from above.

The choice of 8-ounce cups provides good visual impact while remaining manageable to work with. Larger cups would create bolder texture but require more space and material; smaller cups would allow finer detail but take considerably longer to install. The 8-ounce size hits a sweet spot for this type of installation.

Pro Tips for Foam Cup Stage Designs

Layout Planning: Before attaching any cups, create your full layout on one panel and step back to evaluate. Take photos from multiple angles including from the audience perspective. It’s much easier to adjust unglued cups than to remove and reposition glued ones. Consider creating a simple template or jig to help maintain consistent spacing as you work.

Lighting Strategy: The dimensional quality of cup designs creates interesting light play but also potential shadows. Side lighting and uplighting work best for highlighting the texture, while front lighting can flatten the dimensional effect. Test your lighting design before finalizing the cup placement to ensure the texture reads as intended from the audience area.

Paint and Finish: If you want colored cups rather than white, use spray paint designed for foam or plastic. Apply light, even coats to avoid drips. Consider painting the cups before gluing them to the backing—this allows for more even coverage and eliminates the risk of getting paint on the backing board. Allow paint to fully cure before handling to prevent fingerprints and smudges.

Storage and Transport: Foam cup panels are surprisingly durable but should be stored flat to prevent warping. Avoid stacking heavy items on top of them. When transporting, protect the cup surfaces from contact with anything that might crush or mark the foam. With proper care, these panels can be reused for multiple sermon series or seasonal designs.
