Sleeping changed overnight

People say that at Sophie's age, 6 months, things change literally overnight. And it really is true. Sophie has always been a good sleeper, and she still is (knock on wood), but ever since she learned how to roll over consistently (and likes to do it), sleeping has been a bit more of a challenge. She no longer can be succesfully swadled since she just unwraps herself and when she is unwrapped she just goes side to side or end up on her stomach. she hasn't slept on her tummy yet, but I am guessing we will find her that way one of these mornings. I find all this uneasy, it was nice and simple before, we swaddled her, she slept on her back. Now she trashes around wants to pull everything into the crib with her. Any advice out there? What types of blankets should we use?

I haven't worried about her sleeping like this since she was about 2 weeks old. I used to think that I will never be able to go to sleep (due to worrying), but that passed and I guess this will too.

Anyway, thanks for reading, but any advice is always appreciated.
