Crochet blanket edging

I found this blanket recently.I liked color,it was sooo cheap,so i decided to try to crochet edging.I am begginer,so i know only few stitches.I used only double stitch on this blanket.
I turned this...

into this...

I absolutely love the final result.It's so simple.Oh if i'd knew how to make some lace stitch...
