Wild thistles have spiny leaves and tubular flowers that make them tingle when you touch them, making them a bit difficult to approach. However, the fruit is also used for food and medicinal purposes, and when the flowers bloom, butterflies and bees flock to them for the nectar. Honey extracted from thistle flowers is said to have a refreshing taste. I tried to express these wild thistle flowers using a special embroidery technique. This time I asked for embroidery from Pirika in Hiroshima Prefecture, which I have been working with for a long time. This is a long-established embroidery factory founded in 1981. I asked Ms. Pirika, ``Is it possible to use a machine to create expressions that are difficult to embroider by hand?'' and asked her to come up with a method. The most difficult part of thistle embroidery is adjusting the thread tension. Due to the special setup of the machine, only experienced craftsmen can make Pirika. The petals are adjusted so that the thread floats just enough to fit scissors, and then cut after embroidery to create a three-dimensional flower. The thread tension between the petals and other parts is completely different, so the skill of a craftsman who can finely adjust the stitching is essential in order to achieve beautiful embroidery. In addition, the embroidery this time is filled with the wisdom of Pirika, who has been embroidering for over 40 years, such as techniques for cutting without damaging the fabric and creating embroidery data that prevents threads from coming out.
