26. Care and maintenance for proper
drawing
For the achievement of good output we must follow the following steps
First of all you must wash your hand .
Clamp the sheet straight onto the paper with the help of the t square.
Be assure that your drawing board is 90 degree from every side.
Don’t rub your hands onto the sheets.
Don’t rub any type of instrument onto the drawing sheet
Use the compass with the light hand so that it does not damages the sheet.

27. Don’t sharp the pencils over the sheets so that the sheet remains clean.
Before using the instruments clean the instruments .
Don’t put the books over the sheet to avoid any damage.
When you rub the any shape then use the eraser lightly so that it does not damage the sheet.
Use the tissue paper to remove the erased material from the sheet.
