Not sure if this should be here, or under Beginners...but i'm putting it here 
Can someone please help me with step 4 in the roux method? i can easily get there, but once there i don't understand roux's explanation of it. I can tell whether the edges are oriented correctly or not, but i don't know how to fix the orientation. I don't understand how to permute the edges either...maybe i'm just slow, but i really don't understand roux's explanation of it.
Any help is much appreciated!
