Tap bottle firmly (tip downward) on hard surface.  Flush out bottle by squeezing out a small amount of paint, and wiping tip clean.

Preprinted paper towels or napkins are great for practicing linework.  To create dimensional lines, hold bottle like a pencil and gently hold tip to paper surface, squeezing and moving bottle simultaneously over preprinted lines.

For raised linework:  Hold bottle at an angle, allowing more paint to escape and pull across paper.

For a flatter line hold the bottle straight up and down, allowing less paint to escape.

To make a comma shape, hold bottle straight up and down.   Squeeze and pull toward you and squeeze out a dot of color, pulling it toward you and quickly releasing pressure.  Paint will naturally form a graduated tip.

A comma can turn into a heart by adding a second comma as a mirror image with tips touching.

Replace bottle in convenient CapStand to keep air bubbles flowing to back of bottle.
