After seeing all of the excellent scrim work some of you do I was hard pressed to show my first attempt at scratching a horn but I am a man of my word and here are some pics.
My vision was a colonial Rev War era militiamans horn that he may have worked on sitting around a fire or under a tree when he had the chance to draw on one. That being said if I was alive during the 1770s this is the way I would have done it with no formal instruction and my real lack of artistic skills. I have learned a great deal by "doing" and have made many mistakes along the way so far.
All of this was penciled on prior to scratching, nothing was traced only copied from historic drawings and freehanded. I got some of the script fonts off of the web to try and be as realistic as possible. I did the majority of this on my kitchen table with a small pillow to support the horn. I made a few tools from old steak knives, had a set of Exactos and also bought a set of small of carving tools which I reground the points to my liking. I used India ink as recommended by a few people here.
The next time around I am going to have a table mounted magnifying glass and better light, my 56 year old nearsightedness needs all the help it can get.
I have found a new and enjoyable hobby that goes along with my longrifle shooting.
Overall I am pleased with the way it came out and thanks again to all for the advice and encouragement.
Please excuse the pic quality.
The "Join or Die" snake depicting the colonies. 
American eagle with ribbon saying "Join or Die" ( I screwed up the center part of the ribbon and the "or" so it went on the birds belly. Also the Cowpens battle and date ( I went too deep on the P , U and N. 
Sons of Liberty. I think this is the best part of the horn so far.
