Step 1
Create a new A4 file in Illustrator,
in Portrait orientation, and use Arial to type in a capital ‘F’,
in black. Create an outline and set the Stroke colour to grey. To prevent the Brush tool from creating odd shapes later, use the Direct Selection tool (A) and Convert Anchor Point tool (Shift + C) from the Pen tool set to adjust the sharp corners into round ones. Delete the line on the left. Set the stroke to 15 pixels.
