Single accent walls can be overwhelming. Plastering one wall with busy wallpaper might not be the best move. Hendrickson Photography/ShutterstockIsfira Jensen, CEO and principal interior designer at Nufacet Interiors, said single accent walls with prominent, bold patterns have been trendy in bedrooms. "Accent features are usually done with paint, wall coverings, or millwork, which attract most of the attention in this space," the designer told Business Insider. "While this modern technique can certainly add visual interest, using bold and busy patterns on an accent wall can be overwhelming and will dominate the room."
