Displaying Special Instructions field in confirmation email sent to user and admin

How can I display Special Instructions field in emails being sent after a user make an order?
I check on email template and there was only SHIPPINGINFO but Special Instructions wasn't there, and I did enter Special Instructions in that order.
Thanks for your help!

Also, how can we sent these email in HTML format? Or can I at least have it formatted properly in text? I tried \r\n but that doesn't give me new line in any of these email notifications. The emails received was just a bunch of text that is almost unreadable.
