I was wondering what the difference between cotton batting and polyester batting. Thanks! :D

cotton is better! cotton is heavier, more dense, poly is very light, cotton wicks away moister poly does not, cotton will draw up and give your quilt that good old fashioned look snuggly look, poly will not, can you tell I like cotton ?

I like cotton too. It just seems softer to me. It lays out nicer too when you're making a sandwich. I used to use poly, until the first time I used cotton, now I only use poly when I'm doing trapunto.

I don't like poly b/c it beards.
I love the 80/20 cotton poly
I also do a lot of hand-quilting and it looks so much nicer to me using cotton. My opinion only here!

I have used both and they both have their uses. I prefer cotton. It feels better and draps better.

I usually use cotton, but last quilt tried 80/20 and really like it. Would also like to try Hobbs washable wool. Saw some at a quilt shop during a shop hop and it felt so nice...and DH keeps saying he likes "poofy" quilts. I can't get him to understand that what he is referring to are "comforters"! Gotta love him anyhow...he is my enabler ;-)

Cotton is easier to quilt, poly is cheaper.

I actually find poly easier to hand quilt then cotton. I prefer the look and drape of cotton though. However I am currently working a project using Quilter's Dream polyester. It has lovely drape and is very easy to needle.

Also cotton doesn't melt when an Iron touches it where poly on the other hand can make a mess when an iron gets too close.

Some of the polys don't hold up as well through the washer either, they tend to migrate and end up in little wads if you don't quilt quite heavily.
