Saturday, September 20 brought together 21 members of the guild to participate in a 3-day workshop instructed by Bobbie Irwin, of Montrose Colorado. Yarns had been purchased and warps made by Joanne, and everyone warped their own loom. Bobbie presented an overview of the workshop and the theory behind the process of iridescence, which she describes as “a play of colours, where the apparent colour can change with the light and the angle of view”. The weaving began, and continued for a total of 3 days. At intervals Bobbie showed many of her numerous samples, including one that was set at 60 ends per inch. After two days, the weavings came off the looms – they were all beautiful! Then, back to the looms, where we wove a second sampler of weft colours of our choice and treadlings other than plain weave.
