Trekell Gothic Arch Altar Panel – 1/2" Baltic Birch – 6.5" x 12"

Trekell Gothic Arch Altar Panel – 1/2" Baltic Birch – 6.5" x 12" Closed

Trekell Gothic Arch Altar Panel gives artists a unique three-part painting surface inspired by Gothic arches and traditional triptych-style artwork. Two hinged side panels open to reveal the full composition, allowing the artwork to change depending on whether the panel is displayed open or closed.

When closed, the panel measures approximately 6.5" x 12", creating a tall, compact Gothic arch. Open the two hinged doors to reveal a larger 13" x 12" composition with three connected painting surfaces. Artists can create one continuous scene across the open panel, separate imagery on each section, or design the exterior and interior as completely different parts of the same piece.

Constructed from premium 1/2" B/BB Grade Baltic Birch, the panel provides a rigid natural wood surface without the flex of stretched canvas. The surface is pre-sanded with 180-grit sandpaper and left unprimed, giving you control over how it is prepared for your preferred medium and technique.

A CNC-routed keyhole on the back allows the finished piece to hang on the wall, making the opening doors part of both the artwork and its presentation.

Creating with the Hinged Design

The hinged format gives you several ways to approach the artwork. Paint across all three panels to create a larger composition when open, treat each section as an individual part of a triptych, or use the closed exterior and open interior to reveal different imagery.

The format works especially well for narrative pieces, portraits, sacred or icon-inspired artwork, fantasy, dark art, botanical subjects, surreal work, and compositions where the act of opening the panel can become part of the finished piece.

Preparing Your Panel

This panel arrives unprimed so you can prepare the surface for your preferred medium. Oil and acrylic artists can seal and prime the Baltic Birch with their preferred ground, while watercolor artists should apply watercolor ground or mount watercolor paper to the painting surface.

For techniques where you want to incorporate the natural Baltic Birch into the artwork, the pre-sanded surface can be left visible as part of the finished piece.
