How to add horns onto a character I'm trying to model one of my D&amp;D characters in blender. I've already thrown together a rough reference sheet, and I've gotten decently far on her head. I'd like to at least rough out her horns before I move onto the body, but I realized that I made a grave mistake: I have no clue how to extrude part of her head in a way that would let me shape her horns how I want without wrecking the mesh.
 Is there anything I can do to work around this? I'd really like to keep it all as a single mesh, if possible.
Please let me know if you need me to elaborate on anything, or provide something to help!
You need to make sure that you have enough geometry, i.e. 4 squares, then you make a 8 vertices circle (ShiftAltS to transform to sphere) that you can extrude.
