The art of weaving ulos is a skill passed down through generations, often from mother to daughter. Each pattern—be it geometric motifs, zigzags, or floral designs—has its own name and meaning. Colours too are symbolic: red for bravery, black for wisdom, and white for purity. The motifs and colors woven into Ulos carry profound meanings. For instance, red signifies courage and strength, black denotes wisdom, and white represents purity. Patterns such as Gorga (carved wood motifs) are mirrored in Ulos, linking the textile to the Batak’s architectural and spiritual heritage.

In modern times, ulos has transcended its ceremonial use. Fashion designers and cultural advocates have incorporated ulos into contemporary clothing, accessories, and home décor, helping to preserve the craft while making it accessible to a wider audience. Yet, despite these modern adaptations, the essence of ulos—as a tangible link to Batak tradition—remains intact.

Ulos has transcended its traditional role, finding its place in contemporary fashion and design. Designers incorporate Ulos patterns into modern garments, accessories, and home décor, bridging the gap between tradition and modernity. This fusion not only preserves the craft but also introduces Batak culture to a global audience.

In recent years, the rise of synthetically dyed Ulos Batak has threatened the survival of traditional, naturally dyed handwoven textiles. Synthetic dyes allow for brighter, faster, and cheaper production, but the process involves harsh chemicals that can damage fibers and pollute the environment. Meanwhile, naturally dyed Ulos—crafted with plant-based colors extracted from roots, leaves, and barks—requires meticulous labor, patience, and deep knowledge of local flora. The convenience and low cost of synthetic alternatives have led to a decline in demand for natural Ulos, endangering not only the craft itself but also the cultural and ecological heritage embedded in each handwoven piece.
