Desperately in need of a new born baby

I once saw these fabulous blankets at a local kids garage sale/small business sale. They were called butterfly blankets. The idea was that it would make swaddling easier. they had a pocket to put baby's legs in so that they couldn't kick it free and then you just wrapped them up. I loved them, but I also thought they looked to bulky for a new born. My newborns love to be wrapped up tight, and I just couldn't see how I would get these blankets tight enough. So I have been thinking a lot these past few nights, cuz I do that when I am pregnant, think for hours on end at night while I lay in bed trying to sleep. So I've been thinking about how I might be able to create the same kind of idea, but more like a receiving blanket.

Yesterday I decided that I had had enough thinking and it was time to start doing(strangely enough I slept quite well last night). I found in my stash some ugly cotton fabric that I had gotten from my aunt years ago when she was cleaning out her fabric stash. I've kept it around for just this kind of thing when I don't want to waste perfectly good fabric that actually cost me money. I started measuring and cutting and more measuring and in the end I came up with this...
and then you wrap up your baby like this...

OK, so I know it works great on a Cabbage patch doll. It wraps up easily and it's not bulky. I know that some baby's are actually about the size of a cabbage patch doll...but not my babies. I planned for this, however I wasn't convinced in the end that I had allowed enough extra room. Also, a cabbage patch doll doesn't kick and squirm, so I can't tell if it will stay wrapped up any better than a regular receiving blanket. This is where the need for a new born comes in, I want to have this tested out before my little one arrives. I'd also like to start selling them in my Etsy shop, but I need to know how they work in the real world. Can you believe that I don't know anybody close by with a somewhat newish baby? My sister-in-law is due in March, but that doesn't help me right now....oh the troubles.
