This is kind of hard to explain in words, but I've attached a rough sketch of what I'm trying to make, so hopefully that will help. The project I'm working on is one of those blanket dolls where the "body" is a blanket but there's a stuffed animal or doll "head" on top (sorry, I don't know what they're actually called, but you can see my point in the sketch I've attached). I want the blanket portion to represent the doll's dress, so I'd love it to have a scalloped edge around the bottom/outer portion of the circle. However, all the patterns I've found online are for much smaller "scallops", as opposed to just 7 or 8 around the entirety of the blanket. Basically, what I'm trying to make is something similar to a round ripple-patterned blanket, but with the edges being rounded instead of pointed. I've been crocheting for years and know how to read patterns if anyone has one I could use, but I just haven't been able to find on online. Thanks for your help!
Here's a very rough sketch of the final project. I'd like the "base" of the doll (i.e. the blanket portion you can see more clearly in the top view) to be about 10'' in diameter. Sorry I'm not the best artist, but hopefully this gets the point across:
