i've never used wool batting, but i do remember blocking wool sweaters after they were washed.
wet the quilt again. not soaking/dripping wet. then block it. you'll need to lay it out on a flat absorbent surface ... like a mattress (with towels under, an plastic under that, to protect the mattress.) gently pat and stretch into shape. stick pins into it all the way around so it will hold that shape while it dries.
if you gift it, make sure to include laundry instructions.
