Indexing colour in the technique of weaving was the departure point of this research. The Index Collection is series of tea towels and blankets. The total collection consists of 3 different colour series. Each series follows the same process, from Monotone, to Duotone, to Multitone, with the first shade taking the lead and a new tone will be added in the following step. The 'index' is especially designed to translate the amount of colour within each surface, by the usage of squares representing 10% to 100%.
