to cut paper along its working edge. A slight
nick at the edge will ruin the T-square.
Wipe off the surface and edges of your Tsquare and triangles before and after using
them.
Avoid dropping your compass, divider and
technical pens.
Provide a place to hang individually your Tsquares, triangles, protractors and French
curves after using them.
21. Provide
a separate container for drawing
pencils, compasses, dividers, rolling pens
and technical pens.
Wash the nibs of your compass after using
them.
Dry the compass nibs and needlepoint after
washing. Store them in a dry place. This will
