adopted as they became available. Starting in the 1890s, the Alaskan Iñupiat began to make use of elaborate decorative trim on almost all their garments, often in bands of geometric patterns which they called . When traders brought rolls of colourful fabric trim, the Iñupiat incorporated pieces of it into . When the style spread east into Canada, it acquired the name "delta trim", possibly in reference to the Mackenzie Delta. The Kalaallit of Greenland are particularly known for a decorative trim known as , or skin embroidery, in which tiny pieces of dyed skin are appliquéd into a mosaic so delicate it resembles embroidery. While somewhat visually similar, it is unclear if and are related techniques. Another Kalaallit technique, slit weaving, involves a strip of hide being woven through a series of slits in a larger piece of a contrasting colour, producing a checkered pattern. Some skins were coloured or bleached. Dye was used to colour both skins and fur. Shades of red, black, brown, and yellow were made from minerals such as ochre and galena, obtained from crushed rocks and mixed with seal oil. Plant-based dyes were available in some areas as well. Alder bark provided a red-brown shade, and spruce produced red. The dying process also made the boots more water-repellent. Lichen, moss, berries, and pond algae were also used. Skins could also be tanned with smoke to make them brown, or left outside in the sun to bleach them white. In modern times, some Inuit use commercial fabric dye or acrylic paint to colour their garments. Many Inuit groups used attachments like fringes, pendants, and beads to decorate their garments. Fringing on caribou garments was practical as well as decorative, as it could be interlocked between layers to prevent wind from entering, and would weigh down the edges of garments to prevent them from curling up. The paw skins from animals like wolves and wolverines were sometimes hung decoratively from men's belts. Pendants were made from all kinds of materials. Traditionally soapstone, animal bone, and teeth were the most prevalent, but after European contact, items like coins, bullet casings, and even spoons were used as decorations. Inuit clothing makes heavy use of motifs, which are figures or patterns incorporated into the overall design of the garment. In traditional skin clothing, these are added with contrasting inserts, beadwork, embroidery, appliqué, or dyeing. The roots of these designs
