I don't prewash my batting, I like the pucker it gives once it shrinks a little after its all put together...

I use warm and natural and never wash it first.

Cotton batting does shrink a little bit when washed. That's how you get that "old" look to a new quilt...by not washing the batting until after the quilt is made. I never pre-wash my batting, but always pre-wash my fabric, because different fabrics shrink differently, and I don't want any unexpected puckers showing up after the first wash.

I've never washed mine. I sometimes put a very wet wash clothe in the dryer with my batting to get the wrinkles out.

I use Warm and Natural or Warm and White batting. I preshrink mine before I use them. I just put the batting in the washer in HOT water and let it soak for about 30 minutes and keep pushing it down in the water until it is wet enough to stay under. (It floats). I do NOT let the washer agitate. Then, I spin it out and put it in the dryer. I think it make the batting softer and since I hand quilt, it's easier to needle.

Don't wash poly wadding but do wash felt and warm and natural,in the bath if large, no wringing BUT towel dry and lay flat draped over airer from ceiling in the utility room.

I use warm and natural, never washed it.

If it has to be prewashed, then it's too much work for me. I use the bamboo batting from JoAnns and have never prewashed. Don't have any problems with it. The label says it can be prewashed for shrinkage, but I'm not going there.

The ones I use usually say pre-washed on them & they never shrink when I wash the quilt! Most are from Joann's. :-D

I have soaked it then gently extracted the water and dried it because I did not want that wrinkly look.
