Sleep sack to blanket

Our girl is pretty tall (90th percentile and already in 24 month pajamas) and is on the verge of becoming too big for the largest sized sleep sack we can find. She moves around a lot at night and I feel like a blanket will just get pushed aside in her crib. Anyone have any tips for transitioning from sleep sack to blanket?
