It looks great! I've got a new Ergo but I've thought about doing a buckle tai so I can make it look super cute. My Ergo is comfy but plain. I love the fabric you used.
I've never seen one with padded straps that cross in the back. My Ergo has a buckle thing that kind of makes an "H" shape out of the two parallel straps. Is it comfy with the padded straps crossing? Have you tried back carrying with it? What did you use and where did you get the buckles?
For anyone else still wanting to make this, I saw a Mei Tai pattern at Hobby Lobby on sale for $2 yesterday. I think it was by McCall's. That may be old news, but it's the first I've seen in a store, and the price was sure right. I thought about using it to make a buckle tai instead but I'm a little intimidated by the thought of trusting it to hold my baby when I sewed it. Now I'm curious about how the x-straps worked out.
