Draw a horizontal line about 70 mm long, and then another six lines underneath, each separated by about 10 mm.

Draw a vertical line about 70 mm long, and then another six lines beside it, separated by about 10 mm.

Draw a faint dotted line in a 70 mm square, and then draw diagonal lines inside the square, separated by 10 mm.

Draw one horizontal and one vertical line in a cross shape. Check the angle in the middle to see if it’s square once you've finished.

Draw the cross again, and then add two diagonal lines. Check the two right angles in the middle are square.

Draw a square, with each side about 70 mm long. Check the corners are square when you've finished.

Draw another square, as above, and then draw a diamond on top. Check all corners are square when you've finished.

Draw a cross 100 mm x 100 mm. Mark 50 mm from the centre in all four directions. Then draw four separate arcs, so that they meet up as a circle.

Draw one horizontal and one vertical line, each 70 mm long, meeting at one end. Then draw five concentric arcs, separated by 10 mm.

Draw a faint dotted line 50 mm x 50 mm square. Then draw a series of continuous loops inside the box.
