With Olympus's new thread dyeing system, you can simply draw on the thread with their developed markers, giving you good control over the process. You also don't need to boil water or similar. The colors are mixed directly in special markers with water. Easy and fun to work with!
With these color pouches, you can choose your favorite colors to use as they are or mix your own colors directly in the markers used to apply the color.
You can find the markers here.
You can find the special thread made for these colors here.
