I botanical dye Olympus Sashiko threads as they are made from 100% cotton and are of a superior quality. I create a wide range of colours that can be used for sashiko, candlewicking, patchwork and quilting. I wind my dyed Sashiko thread onto bobbins containing approx 20 metres of thread.
As with all of botanical dying although the thread may be one colour it can have variations in the tone which adds the the uniqueness of the thread and your final creation.
