I use many different battings for different kinds of quilts but like a poly one for baby and kid quilts, it's nice and soft and lightweight. I know these will be put in the washer and dryer many, many times and poly is quick drying. DGD Josi has one I made 12 years ago and the poly batting has held up wonderfully. Check on the batting package as to how close your quilting needs to be - this will keep the batting in place. One problem some have had with poly batts is that it can 'beard' through dark fabrics in your quilt, that is you'll see some white fuzzy beard like stuff on the dark fabrics. Dream Quilters has great poly batting and I've never had it "beard" on me. May in Jersey
