The most important thing to remember with your letter head is to keep it in a matching theme with all of your other items. Everything needs to look as if it is a set, so they all need to match perfectly. Colour tone, logo, all of it. Sometimes the coloured paper will be a problem, font may be hard to read on it, and it can be very costly at times, so take all of this into consideration when designing your letter head.
Remember to have it simple and appropriate towards your company at all times. Don’t take up the entire page with your letterhead, and don’t make it all too joke filled, remember there are chances of you having to send a serious letter out with this too.

Double sided paper will be okay, just remember your cost on this part too. Also remember that there is a chance you may have to print on the back of the page at some point, so take the colour you use into consideration.
