A letterhead is a heading that often goes at the top of a business letter. It usually consists of the company logo and contact information, such as the company name, address, phone number and website. A well-made logo gives the appearance of professionalism and authenticity -- two things necessary when logging volunteer hours. To put together a letterhead, all you need is a computer and a word processing or graphics programs.

Microsoft Word

Open Microsoft Word on your computer. From the formatting toolbar, choose a font, font size and font color for your letterhead.

Type your company name on the first line. Type your company address in the second line. Type your city, state and zip code in the third line. Type your company phone number in the fourth line; you can also include a fax number. Type your company website address in the fifth line; you can also include an email address.

Highlight the entire text of the letterhead. From the paragraph toolbar, choose the center text option. Save your letterhead and insert it as a header for future business letters, such as volunteer verification letters.

Adobe Illustrator

Open Adobe Illustrator on your computer. From the menu screen, select the template option. Click on a template to see a preview of each letterhead. Choose a letterhead template.

Fill out the template with your company information. From the edit menu, change the font, font size and font color.

Save your template from the file menu at the top of the screen. Insert the letterhead as a header for future business letters. To insert the letterhead into word processing documents, copy and paste the letterhead into the header section of the business letter.
