I just wanted to post that I wanted to try a pouch/sling, but don't really have the $$ to buy one so I found a pattern online (below) and decided to try it. I am not at all good at sewing and consider myself a novice and it turned out great and DD loves it just like the Moby, but it is great for quick trips (easy on/easy off and not hot).
