What You'll Learn
Preparing the Styrofoam Head Surface
The styrofoam head's surface must be meticulously prepared to ensure the plastic wrap adheres evenly and securely, creating a smooth foundation for expansion. Begin by inspecting the head for any imperfections, such as dents, cracks, or rough patches. These flaws can compromise the final result, causing uneven stretching or visible distortions. Use fine-grit sandpaper (220-grit or higher) to gently smooth out any irregularities, working in circular motions to maintain the head’s natural contours. Wipe away dust with a damp cloth and allow it to dry completely before proceeding.
Next, consider the role of a base coat in enhancing adhesion. While not strictly necessary, applying a thin layer of acrylic gesso or primer can significantly improve the bond between the styrofoam and the plastic wrap. Use a small brush or sponge to apply the primer evenly, ensuring full coverage without pooling. Allow it to dry for at least 30 minutes, or follow the manufacturer’s instructions for optimal curing time. This step is particularly useful if you plan to apply multiple layers of plastic wrap or if the head will be subjected to handling or stress.
A critical but often overlooked aspect is the temperature and humidity of your workspace. Styrofoam is sensitive to heat, and plastic wrap can become brittle or lose elasticity in cold conditions. Aim for a room temperature of 68–72°F (20–22°C) and moderate humidity (40–60%) to ensure both materials perform optimally. Avoid working near heat sources like hair dryers or heaters, as direct heat can warp the styrofoam. Conversely, if the plastic wrap feels stiff, gently warm it with a hair dryer on low heat to increase pliability before application.
Finally, plan the direction and tension of your plastic wrap layers. Start by wrapping the head in a single, taut layer, overlapping the edges by no more than 1/4 inch to avoid bulkiness. Use clear plastic wrap for better visibility of the underlying surface. For areas requiring more expansion, such as the cheeks or forehead, apply additional layers in a crisscross pattern, smoothing out wrinkles as you go. Secure the wrap temporarily with pins or tape, but avoid puncturing the styrofoam. Once the desired shape is achieved, seal the layers with a light coat of spray adhesive or diluted white glue to prevent shifting during further modifications.

Applying Plastic Wrap Layers Evenly
Achieving an even application of plastic wrap layers is crucial when enlarging a styrofoam head, as uneven layers can lead to lumpy or distorted results. The key to success lies in maintaining consistent tension and overlap as you wrap. Begin by tearing off a sheet of plastic wrap approximately 18-24 inches in length, ensuring it’s long enough to encircle the head with some excess for overlap. Hold the wrap taut but not stretched to its limit, as over-stretching can cause it to snap or lose its shape. Start at the base of the head and work upward, overlapping each layer by about 50% to create a smooth, uniform surface.
The technique for applying plastic wrap evenly is as much about patience as it is about precision. Move slowly, smoothing out any wrinkles or air pockets as you go. Wrinkles can become permanent once additional layers are added, so take the time to press them flat with your fingertips. For hard-to-reach areas, like the crown or nose, use smaller pieces of wrap and apply them in a crisscross pattern to ensure full coverage. Avoid pulling the wrap too tightly, as this can distort the underlying styrofoam; instead, aim for a snug fit that maintains the head’s original proportions.
A comparative approach can help illustrate the importance of even layering. Imagine wrapping a gift—if the paper is applied haphazardly, the result is messy and unprofessional. Similarly, uneven plastic wrap layers on a styrofoam head will compromise the final shape and texture. By treating each layer as a deliberate step in a larger process, you ensure the end result is cohesive and symmetrical. Think of the plastic wrap as a foundation; just as a builder levels the ground before constructing a house, you must create a smooth base before adding additional materials like clay or plaster.
To troubleshoot common issues, keep a pair of scissors handy to trim excess wrap and a spray bottle of water to lightly dampen the plastic if it becomes static-prone. Static can cause the wrap to cling unevenly, so a light mist can help it lay flat. Additionally, working in a cool, dry environment minimizes the risk of the plastic sticking to itself. If you notice a bulge or uneven spot after several layers, carefully peel back the wrap to the problem area and reapply, ensuring proper tension and overlap.
In conclusion, applying plastic wrap layers evenly requires a combination of technique, attention to detail, and problem-solving. By maintaining consistent tension, smoothing out imperfections, and addressing issues promptly, you can create a seamless base for enlarging your styrofoam head. This step, though seemingly simple, is foundational to achieving a professional and polished final product.

Smoothing Out Wrinkles and Bubbles
Wrinkles and bubbles are the bane of any styrofoam head enlargement project using plastic wrap. These imperfections not only detract from the aesthetic appeal but can also compromise the structural integrity of your creation. Understanding the root causes—such as uneven tension, trapped air, or improper layering—is the first step to mastering the smoothing process. Addressing these issues requires a combination of technique, patience, and the right tools.
To effectively smooth out wrinkles, start by warming the plastic wrap slightly with a hairdryer set on low heat. The warmth softens the plastic, making it more pliable and easier to manipulate. Work in small sections, gently pulling and smoothing the wrap as you go. Avoid overstretching, as this can lead to tears or thinning of the material. For stubborn wrinkles, use a blunt tool like a spatula or the edge of a ruler to press and flatten the area without puncturing the wrap.
Bubbles, on the other hand, are often caused by trapped air during the wrapping process. To prevent them, ensure the styrofoam head is clean and dry before beginning. Apply the plastic wrap in thin, even layers, smoothing each layer with your hands or a flat tool as you go. If bubbles do appear, carefully lift the wrap at the edge of the bubble and press the air out toward the opening. For larger bubbles, a pin can be used to puncture the wrap, but this should be done sparingly and only when necessary, as it creates a weak point.
A comparative analysis of smoothing techniques reveals that combining heat with gentle pressure yields the best results. While some DIY enthusiasts swear by using a heat gun, it’s too easy to melt the styrofoam or warp the plastic. A hairdryer, on the other hand, provides controlled heat that’s safer and more effective. Additionally, pairing this method with a light mist of water on the wrap can enhance its pliability, though caution must be taken to avoid saturating the styrofoam.
In conclusion, smoothing out wrinkles and bubbles is a delicate balance of technique and tools. By warming the plastic wrap, working methodically, and addressing imperfections as they arise, you can achieve a seamless finish. Remember, the goal is not just to enlarge the styrofoam head but to do so with precision and care, ensuring the final product is both functional and visually appealing. Practice makes perfect, so don’t be discouraged by initial imperfections—each attempt brings you closer to mastering this craft.

Securing Wrap with Adhesive or Tape
Securing plastic wrap around a Styrofoam head requires precision and the right adhesive or tape to ensure a seamless, durable expansion. Double-sided tape, particularly the thin, acid-free variety, is ideal for this task as it adheres firmly without adding bulk or leaving residue. Apply the tape in strips along the edges of the wrap, pressing it gently to avoid air bubbles. For a more flexible hold, consider using a low-tack adhesive spray, which allows for repositioning during the wrapping process. However, be cautious with sprays near Styrofoam, as some solvents can dissolve the material.
The choice between adhesive and tape hinges on the desired finish and the project’s longevity. Tape offers a cleaner, more controlled application, making it suitable for detailed shaping or temporary displays. Adhesive, on the other hand, provides a stronger bond for long-term projects but requires careful application to avoid oversaturation. For best results, test both methods on a small area of the Styrofoam head to determine which adheres better without damaging the surface. Remember, the goal is to secure the wrap tightly enough to maintain the enlarged shape without causing the Styrofoam to warp or crack.
When using tape, opt for a matte finish to minimize visibility under the plastic wrap, especially if the head will be painted or decorated afterward. Clear tape can be used if the wrap is opaque or if the project prioritizes functionality over aesthetics. For adhesives, choose a product specifically designed for lightweight materials to prevent the Styrofoam from becoming too heavy or misshapen. Always apply adhesive in a well-ventilated area and follow the manufacturer’s instructions for drying times to ensure a proper bond.
A practical tip for securing wrap with tape is to create a grid pattern on the Styrofoam head before wrapping. This involves placing strips of tape horizontally and vertically, leaving enough space between them to allow the wrap to conform to the head’s contours. Once the wrap is in place, smooth it over the taped areas, pressing firmly to activate the adhesive. This method not only secures the wrap but also provides a structured base for adding additional layers or decorative elements.
In conclusion, securing plastic wrap with adhesive or tape is a critical step in enlarging a Styrofoam head, requiring careful material selection and application techniques. Whether opting for tape’s precision or adhesive’s strength, the key is to balance adherence with the integrity of the Styrofoam. By following these guidelines, you can achieve a professional, long-lasting result that serves as a sturdy foundation for further customization.

Shaping and Expanding the Head Size
Expanding a styrofoam head using plastic wrap requires precision and creativity to achieve a natural, proportional increase in size. Begin by identifying the areas you want to enlarge—cheekbones, jawline, or crown—and mark them with a pencil. Tear off strips of plastic wrap, roughly 6-8 inches long, and layer them over the marked areas, smoothing each layer to avoid wrinkles. The wrap acts as a moldable base, allowing you to gradually build volume without distorting the head’s original shape. For best results, use clear wrap to maintain visibility of the underlying structure.
The key to successful expansion lies in controlling the thickness of the plastic wrap layers. Start with a single layer, then add more incrementally, checking the head’s symmetry after each addition. A common mistake is overloading one side, which can create an uneven appearance. To avoid this, rotate the head frequently and compare it to a reference image or the opposite side. For precise adjustments, use a heat gun on low setting to slightly soften the styrofoam, making it easier to mold under the wrap. Always keep the heat source at least 6 inches away to prevent melting.
While plastic wrap is versatile, it’s not a permanent solution. To secure the expanded shape, apply a thin layer of spray adhesive between wrap layers or use a low-temperature hot glue gun to bond the edges. Alternatively, cover the entire head with a thin coat of plaster gauze or papier-mâché once the desired size is achieved. This adds durability and allows for further detailing, such as smoothing edges or adding texture. Remember, the wrap is a temporary scaffold—plan for a final finishing material to lock in your work.
Comparing this method to others, such as carving or adding clay, highlights its advantages and limitations. Plastic wrap is lightweight, inexpensive, and easy to manipulate, making it ideal for quick experiments or temporary projects. However, it lacks the structural integrity of clay or the precision of carving. For long-term displays or heavy use, consider reinforcing the wrap with a harder material. This hybrid approach combines the flexibility of wrap with the durability of more robust mediums, ensuring your expanded styrofoam head stands the test of time.
