Flattened edges refer to the process of smoothing or reducing the sharpness of the edges of an object, making them appear flatter or less defined. This can be achieved through various techniques such as sanding, filing, or grinding. The relief effect, on the other hand, refers to the visual illusion created by adding depth and dimension to an object or design. This can be achieved through techniques such as embossing, engraving, or sculpting, which create a raised or sunken appearance on the surface of the object. Both flattened edges and the relief effect are commonly used in art, design, and manufacturing to enhance the visual appeal and tactile experience of objects. **

The hair is flattened by the headset because the pressure from the headset's ear cups and headband compresses the hair against the scalp. This pressure causes the hair to lay flat and conform to the shape of the head, resulting in a flattened appearance. Additionally, the friction between the hair and the headset's materials can contribute to the flattening effect. **

The new down jacket was completely flattened because it was vacuum-sealed for packaging and shipping. This process removes all the air from the jacket, causing it to become compressed and flattened. Once the jacket is removed from the vacuum-sealed packaging, it can be fluffed up and regain its original shape and insulation. **

The freshly laid turf was completely flattened because it likely did not have enough time to establish its root system before being walked or driven on. Turf needs time to take root and establish itself in the soil in order to withstand foot traffic and heavy objects. If the turf was not given enough time to properly root, it would have been easily flattened by any weight placed on it. Additionally, if the ground underneath the turf was not properly prepared or compacted, it could have contributed to the turf being easily flattened. **

The flattened hufeisen lip frenulum typically has a crescent or horseshoe shape, resembling the outline of a horseshoe. This shape is due to the thinning and stretching of the frenulum tissue, causing it to flatten out and widen. The frenulum may appear elongated and thin, with a broadened base where it attaches to the lip. **
