Why do you need to open the door of your washer before it is finished when washing the batting? I usually just use cool water and no soap in a short cycle to wet the batting or fabric. That way it works for me and no problems.

yes ,always.

i prewashed warm and white on my last quilt i made because even tho warm and white only shrinks 3% i didnt want it to shrink at all the key to washing it so it doesnt fall apart is DO NOT let it agitate in the washer, i just filled machine with warm water let it soak for a while then skipped the agitate let it rinse and spin , put it in the dryer and dried it then used it in what i was making

I do not prewash my batting either. I like to wash the finished quilt and batting all at one time.

I don't pre-wash batting as I like the "crumpled" look for baby quilts. But I always pre-wash the fabric. :lol:

I think there are directions right on the package. Don't use soap or detergent. I prewash mine by putting it on a rinse cycle using cold water. I stand right by the machine while it fills, and stop it before it starts agitating. I think you said you have a front fill, so that would be an issue. Spinning the water out is not a problem. Then I just dry it in the dryer. I've never had a problem. Be prepared for at least 3% shrinkage.

I have always used my front loader machine on delicate cycle so it doesn't have to be in the washer too long but it always comes out beautiful, soft and wrinkle free. I have also washed the bamboo-cotton batting the same way.

Once I used a wool batt and it was like butter to hand quilt. It was a twin size. I hand washed it in the bathtub and laid flat in the yard to dry. It came out perfect. It was given to my son and his wife with the instructions that you can't wash it in the washing machine only hand wash. They took it to the cleaners instead and told them it couldn't be washed. However, they washed it and it was now shrunken down to crib size. They collected a $100 or so from the cleaner and just tossed it in the toy box and used it when someone needed a coverup. However I awoke one night and thought the only thing wrong with that quilt was the batt so I unsewed everyone of my hand stitches. I added another border and put the whole thing together again. They love it and they can wash it with the new poly batt.

Same here. I never pre-wash batting. Sometimes I pre-wash fabric, but not always. Depends if I am using pre-cuts, or if the fabric was cut close..I don't want to run short because of fraying.

Wow!! Never heard of this problem with a washable wool batting!!
