Grain-Enhanced Wood Accents
Lightly texture softwoods like pine to raise the grain and create a weathered, driftwood-like effect before staining. The crimped wire is more forgiving than knotted wire, making it easier to control depth and avoid gouging. Ideal for picture frames, signage backers, and rustic shelving. Test on scraps to dial in speed and pressure.
