This is one of the greatest stamping tips I can give you!
You know when the marker comes fresh and new with the nice sharp point and it's awesome to use?
And then after a few hundred (thousand?) times using it to color directly on the stamp, that nice sharp point becomes smushy & hard to color with?
What we do is take the smushy marker and mark it with a bit of nail polish (the ONLY time you will see nail polish used in this house!). These markers are then used only for coloring directly to the stamp.
That way we have a marker for precise coloring and one for inking our stamps.
