Embossing powder needs heat-resistant backing that won't warp under repeated melting cycles. These pre-primed die-cut boards handle multiple layers of Dyamond Rocks without curling or buckling, maintaining flat surfaces through the heat-setting process that creates those dimensional, crystalline effects. The priming ensures even medium coverage and optimal powder adhesion, no bare spots or patchy melting that ruins otherwise perfect pieces.

Apply medium, add powder, melt with your heat tool; the board stays stable through three full layers and debossing while hot. That stability matters when you're pressing stamped images into melted powder, the board won't flex or shift beneath your stamp, so you get clean, crisp impressions. Die-cut shapes eliminate measuring and cutting, letting you focus on layering technique and design rather than prep work.

Each pack includes twenty identical pieces, perfect for creating matching embellishments for journal covers or producing multiples for mixed media projects. Add finished boards to handmade cards, art journal pages, or anywhere you want that distinctive crystallized texture Dyamond Rocks deliver. The consistent sizing across all twenty pieces means uniform results when you're creating sets or series.
