Concept, Scale & Ambition
Smaug from The Hobbit is one of fantasy cinema's most visually defined dragons — and translating that into a wearable costume requires solving problems that don't have existing solutions. The scale coverage alone exceeds 800 individual pieces. The structural challenge of creating a dragon form that reads convincingly in photographs and in person, moves naturally during the convention parade, and survives a full multi-day event is significant. This was Heidi's most ambitious build to date and remains the most technically complex piece in the portfolio.
Scale Construction: 800+ Individual Pieces
Each scale is individually heat-formed from closed-cell EVA foam at a specific size and curvature determined by its position on the body — the scales on the belly are larger and flatter; those on the spine ridge are taller and more pronounced; those at the limb joints are smaller and more flexible to allow movement. After heat-forming, each scale receives three coats of Plasti-Dip sealer, then a base coat of dark metallic paint, then a dry-brush highlight layer to create the dimensional sheen of Smaug's specific colouring.
The scales are applied to a custom-made base suit in sections — the belly section, the back sections, the arm sections, and the leg sections are each assembled separately and then combined. This allows the costume to be put on and taken off by a single person, which is a practical requirement for convention wear.
Head Construction
The head is the costume's centrepiece — a sculptural form built over an internal structure of aluminium wire and foam, covered in Worbla thermoplastic for rigidity, then detailed with individual scales applied over the surface. The jaw articulates via a cord mechanism that the wearer controls with a hand grip. The eye detail is resin-cast with an internal LED for photography.
Structural Engineering for Wearability
A dragon costume that can only be displayed on a stand is a display piece; one that can be walked through a convention parade for two hours is a costume. The internal structure distributes the weight across the wearer's shoulders and hips through a custom-built harness — no single point bears an unsustainable load. The wing structure (the most weight-critical element) is carbon fibre rod with foam and fabric, weighing less than 2kg total despite a span of approximately 1.5 metres.
DragonCon 2021 Performance
The costume debuted in the DragonCon parade and subsequently competed in the masquerade where it received recognition in the craftsmanship category. Total parade wear time: approximately 2 hours. The construction survived intact — a genuine test of structural engineering at the scale and complexity of this build.

Frequently Asked Questions
This build represents approximately 120+ hours of construction time across concept development, structural engineering, scale production, and finishing. It is the most time-intensive build in the portfolio.
Yes — every scale is individually heat-formed, finished, and applied. The total count exceeds 800 pieces. The scale size and curvature varies by location on the body.
A build of this complexity is a major undertaking — Heidi would consider it as a commission with a minimum 12-month lead time and a significant budget. Contact for a discussion.
