the Hobbs wool battings I have used in the past *relaxed* when I opened them up & draped them over my quilting table. I would take them out of the package the evening before I planned to quilt and drape them --- when I went into the room the next morning they would be relaxed & ready- I've never had any problems with using a batting with some wrinkles- they smooth out just fine when smoothed over the backing- and quilt out just fine. it does seem like there are some instructions on the packaging about this also- or, visit the website & check for hints/tips ; some people toss them into a dryer with a damp towel & tumble /fluff them- I've never done that so no experience with how well that might work.
