Shhh . . . . . . . It's a Secret

I am secretly married and pregnant. Just kidding. But, not. I've been on a baby blanket crocheting kick since Saturday. My sister asked who's babies the blankets were for and I said, "I don't know. Maybe mine." Her friend said, "yeah, didn't you know your sister's pregnant?" "I'm also secretly married," I added. I even wore a ring for part of the afternoon.
I've really enjoyed doing the blankets, but I'm having a hard time finishing them, edging them. I'd really like to do a scallopy edge like is on a blanket I grew up with, but I don't know how. I have enough trouble crocheting squares and rectangles of single-stitches! I've been working on two; one is as big as I want it but I can't do the edge, so the yarns are still attached to it waiting while I work on the second. I hope this doesn't turn out to be one of those projects that get started but never finished.
