Once you have your character looking like how you want the preset to look, hit the tilde key, otherwise known as '~', and type 'SPF YOURCHARNAME', of course substituting the 'YOURCHARNAME' for the name of your character. You can decide whether or not to save your game after this it doesn't really matter in the grand scheme of things. Make sure that you are out of the ShowRaceMenu. Create a character that you would like to share, or open your old save. There is no point in having an empty mod enabled. Whatever you named your mod, you need to go to the mod manager you are using, whether it be the launcher or the Nexus Mod Manager, and uncheck your mod in the load order. I named my mod Solding_CharPreset for the character I am going to be sharing.
When you are finished saving, exit out of your Creation Kit.
