Hobbs 80/20 is the batting I use most of the time. I also like Quilters Dream battings and have used them for special project. I also use good quality poly for baby and kid quilts as they get a lot of washing and I've found they hold up very well. In fact, my 14 year old granddaughter's baby quilt is still in great shape with it's inexpensive fabrics and cheap poly batting. I know her Mom has washed is many, many times and just threw it into the dryer.
