I sometimes pre-wash my wool batting just because it shrinks so much. I have actually had to wash it because it of smoke from my pellet stove getting into my closet up stairs where I stored it...it was black and it was supposed to be white. I washed it on gentle and put it in a warm dryer for about 15 minutes. Came out great!

Ditto! :-)

no

No didn't think I had to.

I buy my batting by the roll from Linda's electric quilt.com and no I don't pre wash and don't intend to, I've never had a problem even with the packaged type I get from HObby lobby and Michaels

I agree. I pre-wash all my fabric, but not the batting, because its where I get my antique look from. With the fabric washed and the batting not I get just the right look for me.

I don't know if I would even attempt to put in a washer. If I wanted to shrink it, I probably would take a bottle of water and mist the batting, then put in dryer.

I use Warm and White batting. I do preshrink it. It washes beautifully if you don't agitate. I soak it for an hour or so in very warm water. I spin out the water. Then it does into the dryer on gentle. I've never had a problem with it falling apart. I do longarm quilting. I don't want my finished quilts to shrink. All fabrics get a prewash, too. Fabrics can bleed, especially batiks. I press them using Mary Ellen to get the crispness back prior to cutting.
Any batting with cotton will shrink. I've not tried wool. I imagine there is shrinkage with it too.

I use the wool batting & love it!! I to love the crinkled look! I do prewash my fabric but not my batting. After my quilt is finished I wash & dry it once. Then I give instructions to the recipient to never put it in the dryer from the washer, how ever if it has grass on it or cat or dog hair a good trick for getting these off is to stick it in the dryer dry & tumble for a 15 or 20 minuets. This way it wont keep shrinking like wool does.

IF using a cotton batting and you do NOT want the Crinkled antique look , and you want it to look the same as when you finished it , pre-shrink. I do not like the crinkled look for table runners , I like them to be a smooth as possible. Some "modern" looking quilts it is a preference for me to have them flat, not crinkled. It all depends on what you want the quilted item to look like after its washed.

I haven't. Didn't even know it was possible. Haven't used anything but Warm and Natural so far though and haven't had any problems with washing.

I normally don't pre-shrink batting unless I'm using it in a pot holder or placemat. I made a really nice set of placemats last year. (I used one layer of Hobbs 100% cotton batting.) The first time I washed them, they drew up and won't lay flat any more. I learned!

No I never have.

I ALWAYS wash,NEVER spin but after 2 rinses towel dry and hang flat or over a ""dolly"

It gives you another design option. If I want a quilt that isn't crinkled and I don't want to use a poly batt, pre-shrinking gives me that look.

I threw my W&N into the dryer on medium for about 10 minutes with a damp towel. Then used it. Haven't washed it yet. But I did have to repair one I made a couple years ago with polyester batting and was shocked at how it has lumped up! I'm not using that any more. And I guess I should pay more attention to how far apart to quilt the project.

As my first husband said years ago, "Directions are for the dummies who don't know how to do it." that's me.

Same here.
