I like to applique and have used the white marking pen by Clover. Recently, I purchased a new one in blue made by Pilot. It looks as though I have marked with a ball point pen, but alas, when touched with an iron it goes away as the Clover one does. BUT, using the top of the pen, the marks will disappear with friction or rubbing like an eraser (the iron is easier). This one, obviously, is used to mark on lighter fabrics. The Pilot also comes in black and other colors.
