You're probably knitting it on the inside of your circs so that the knit stitches are on the inside and the purls are on the outside. The points of the needles you're knitting with should be closest to you and the cord, or the other needles if you're using dpns, should be away from you.
Also, with the decreases, there will come a point, when you won't be decreasing 5 every row because there won't be enough stitches to do so.
