Warmaster requires a certain number of markers to indicate which units are confused and how many hits each unit has suffered from combat or shooting (especially when you get into large engagements). Making them can be problematic. So don't bother making any effort. Simply print the picture below, stick it onto some thick card, and cut out the markers.

Just as a point of interest, if anyone has ever wondered how big those Windows icons would be in Real Life(tm), now you know - the markers are the same size.
