Great job - it's very cute!
I've made over 50 Mei Tai's (I used to sell them) and they are so nice to carry babies and toddlers. My suggestions for making them for those that are thinking about it:
1 - Use upholstery thread - it is very hard to break that thread and you want the carrier to be extra sturdy with babies.
2 - Choose your fabric carefully. You don't want it to be too stiff, because it makes it hard to tie. You don't want it to be too thin, because it may rip with weight on it. You don't want it to have too much stretch. I usually went for a thick cotton with just a touch of stretch in it for the straps. The decorative panel on the outside - you can do pretty much any fabric with it - I used embroidered silk a lot (love the pretties!).
I'll have to figure out how to post a tutorial on here that I have written...I just found this site.
