Ikat dying is the process of putting a resist pattern in a weaving by tying and dying the threads in patterns before warping on the loom. Threads are bundled together and put on a warping board, marked with chalk from a stencil, and tied tightly in the chalked patterns. Once the threads have been dyed part of the tied part will be untied, new patterns tied and then the bundles are dyed again. This can happen many times depending on the complexity of the pattern and the number of colors desired. After the dying is finished the threads are warped on the loom and the pattern of the finished weaving will be apparent. Weft ikat occurs when the tied threads are used in the weft of the weave.
