Alter stands for change, in that like a chameleon, it has a tendency to pick up colours from other textiles. As light conditions change, the colour of the curtain appears to change as well. The palette is inspired by tones from Scandinavian nature, ranging from brilliant reds to forest-coloured greens. The sheer, semi-transparent quality gives Alter a beautiful drape with a soft touch, and the yarn-dyed multicoloured quality of the fabric lets warm and cold tones harmonize together. Alter is easy to combine with denser curtains, and it pairs well with Dual, Grain, and Basal.
