Rigid aluminum backing transforms Legion's 100% cotton Stonehenge paper into a portable studio surface that doesn't buckle, warp, or require stretching. The 250gsm cotton sheet bonds permanently to the panel, maintaining Stonehenge's characteristic ability to absorb multiple layers of wax and oil-based colored pencil without waxy buildup, a quality that's made this paper a favorite among Colored Pencil Society of America members. Cotton fibers pull pigment into the surface rather than letting it sit on top, enabling the deep layering and burnishing techniques that colored pencil work demands.

The aluminum backing provides crucial stability for wet media applications. Watercolor washes sit and dry evenly without the cockling that plagues paper-only surfaces, while the non-porous backing prevents moisture from penetrating through. This construction handles aggressive techniques, heavy pencil pressure, solvent blending, repeated corrections, that would damage unsupported paper. The rigid format works beautifully for plein air painting and location sketching, eliminating the need for boards or backing supports.

Archival cotton composition ensures permanence without the premium typically attached to museum-grade surfaces. Mixed media artists appreciate the versatility: graphite, ink, gouache, and acrylic all perform predictably on this neutral white surface that doesn't compete with your color decisions.
