I used to always use polyester because it was cheaper. Then I got started using Warm and Natural. Fabrics seem to adhere to it and I love it. It is more expensive, but oh well.

does this mean you like the dream green?? thanks for all the advice....seems like you're giving a very researched opinion...I like that!

I am so glad that I found this post. I had always preferred cotton. Then I read or heard someone say that cotton is much harder to work with. I will go back using cotton after reading the different post here. However, there are some things that I will still use the poly.
Thanks again for all of the in put. And thanks to the person who ask this question.

Just wanted to remind everyone never to use polyester batting in a child's quilt. It is a fire hazard because it melts and sticks to the skin.

The ultimate batting is silk, but it is very pricy. I'm making a silk jacket and using this batting for hand quilting.

There is a warm & white as well as warm & natural, I really like them both

Thank you for mentioning that, I was going to as well. Please no poly for children!!! And, honestly I won't use it at all for that reason. It will melt on an adult just as easily, so unless the quilt is for something other than sleeping under, no poly for me.

Wow, thanks for this advise. I had not thought about that.
Another good reason to use cotton batting.

I've started to use two batts in my "to show" quilts. A very thin cotton batt (against the backing) with a wool batt over the top. Then I can do fancy quilting patterns and quilt the background behind these fairly heavily. It then give the effect of trapunto without all the cutting out that is usually done.

The biggest problem with Poly for me is the way it catches in my equipment. But it is nice to use in a puffy quilt because it is so lofty. I usually use cotton or fleece.

I'm with Kathy for all her reasons. I prefer the cotton over polyester.
