Welcome to the Quilting Board!
I only use Hobbs 80/20. It seems lighter in weight than others but is still toasty warm. It does shrink when washed due to 80% cotton to give it a "crinkly" look but the poly in it lets it keep its shape. It it easy to sew though. Hobby Lobby carries it both in store and on.-line. Price is reasonable with 40% coupon. Some times HL has free shipping as does Connecting thread with $50 purchase. Try it you'll like it!!!!! It is always nice to have many choices so make samples with quilting of all battings you could use so customer could see the difference.
When the speaker from Hobbs visited our Ranching Heritage Museum last summer for a lecture on batting, he mentioned that 80/20 is their best selling batting.
