I'm working on a poly sphere of a head and trying to pull a neck out of the bottom. I've hidden all but 4 of the polygons and am trying to use the "Edge Loop" button to give me more inner rings of polygons to pull down for the neck. Every time I click the "Edge Loop" button, instead of nice inner circles, I get jagged polygons sticking out of my selection. What am I doing wrong? Thank you for any help.
