Trekell Gothic Rounded Arch Altar Panel – 1/2" Baltic Birch – 9" x 12"

Trekell Gothic Rounded Arch Altar Panel – 1/2" Baltic Birch – 9" x 12"

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

When shut, the panel measures approximately 9" x 12". Open the two hinged doors to reveal a larger 18" x 12" composition with three connected painting surfaces. Artists can create one continuous scene across the open panel, treat each section as its own composition, or use the exterior and interior to reveal 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 hinged 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 rounded arch format works especially well for portraits, narrative pieces, landscapes, florals, botanical subjects, sacred or icon-inspired artwork, fantasy, surreal work, and compositions where opening the panel becomes part of the finished artwork.

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.
