IMIRT,' 'iomairt,' 'iumairt,', 'umairt' is cloth striped lengthwise, not crosswise. While the warp of the 'iomairt' is composed of stripes of various colours, the weft is confined to one - generally light blue, dark blue, or black. This cloth was confined to women's use, in the 'earasaid,' the 'tonnag,' the 'guaileachan,' and the petticoat. Setting the 'iomairt,' like setting other warp, and setting the eggs, and many other operations of the people, was done on Thursday, that being the day of St Columba. Framing the web is a work of much anxiety to the housewife, and she and her maidens are up very early to put the thread in order.
The thread of the 'iomairt,' like that of the tartan, was very fine, hard-spun and double twisted, rendering the cloth extremely durable.
