gaiter

I have been struggling with this stupid brioche stitch that I simply cannot understand how to do. I have the pattern for the Brioche Gaiter in Camelhair from interweave knits fall magazine. I have attempted it several times over and it keeps ending in nothing but frustration! How the heck do you yarn over the first stitch on the needle anyhow?? If anyone out there can come to my rescue-please tag me! I need help! I have some nice handspun angora in grey, that I would love to make into this gaiter....but it is not going to happen unless I get some help....sending out an s.o.s.
