Drawing paper must be set up on a drawing board using a T-square. Once in position, the paper is clipped to the board with board clips or even masking tape.

1. The T-square must be placed up against the edge of the drawing board. There must be no gaps otherwise the paper will not be set up correctly and drawing accurate horizontal and vertical lines will be impossible.

2. The paper is then allowed to rest on the T-square. Check that the paper rests properly on the T-square and that there are no gaps between the T-square and the paper OR the T-square and the side of the drawing board.

The clips can then be positioned holding the paper securely to the board.

3. A 2H pencil can then be used to draw faint horizontal lines across the page. Try to keep the lines to the same size by measuring them with a ruler.
Each time you draw a line check that the T-square is pressed completely against the edge of the board. There should be no gaps.

4. To draw vertical lines a T-square and set square are used together.
Be careful to check that there no gaps between the T-square and the board AND the set square and the T-square. Do not draw vertical lines with a set square only as they will not be accurate.

Great care should also be taken to ensure that the paper does not move. This can happen if a hand or arm rubs too strongly against the paper. Check that the paper has not moved by placing the T-square at the bottom edge of the paper. Then check that the paper rests level against the T-square and that the paper is not at an angle. Ensure that the T-square is also firmly against the edge of the board.
