The Clover Fine White Marking Pen will easily replace all of your other marking tools. This pen is an ink based pen, so it never needs sharpening, and won't disappear if you have to wait a while to finish your project.
Best of all, the ink from the Clover Pen disappears with water, and the ink will also disappear when you iron! (A saving grace for those of use who don't always wash their finished pieces).
