Common types of decorative accessories include throw pillows, cushions, vases, candles, figurines, sculptures, wall art, mirrors, rugs, and decorative trays. Each of these items can add personality, texture, and visual interest to a space, enhancing its overall ambiance.

Decorative accessories can be used to tie together a room's design theme by incorporating elements that echo or complement existing colors, patterns, and styles. For example, selecting throw pillows in coordinating colors with the sofa upholstery or choosing vases that reflect the room's accent colours can create a cohesive look and feel.

When arranging decorative accessories, consider balance, scale, and proportion. Group items in odd numbers, vary heights and sizes for visual interest, and create focal points by placing accessories strategically. Additionally, use contrasting textures, colors, and shapes to add depth and dimension to your arrangements, and don't be afraid to experiment with different layouts until you find one that feels harmonious and visually appealing.
