Step 1: Get some Scrimshaw stuff to etch or carve

You will need something to etch or carve. Usually, shell, bone, antler, or ivory. I have tried, bone ,antler,  teeth, ivory, polymer (ivory simulation), shell and glass! I found an old piano that had real Ivory keys. What a find! Then I found some keys that look exactly like the Ivory ones, but they were polymer plastic look- alikes. You can test for real ivory by heating a needle, held with plyers till red hot on the end. Touch to the key and if it goes into it easily its plastic, the Ivory will not puncture or melt like the plastic ones. Also grind and edge,  one will smell like plastic and the other won't.

Step 3: Get to work (its fun)

Get comfy, some good lighting is essential, relax, you can't rush this! Choose a subject. Sailing ship, whales, seashore scenes, lighthouses, dolphins, mermaids, etc... Anything  that you choose. I did a Lion, in reverse Scrimshaw once. The background was black and the lion was white. See pict. 

Step 4: Blacken the Ivory

You must blacken the Ivory to see what you have etched. Shoe polish or soot & oil mix, or crayon will work. Remember once you etch its not eraseable. So sketch in pencil first and have pics and drawings at your side for reference.

Step 6: Get some pics to look at

Get some pics of the subject you want to etch. The more the merrier. Remember you have to shrink it down to fit on your Ivory, shell, or bone. Steady hands and sharp eye! Practice on a scrap piece first. You will get better as you go.
