I had the same problem with Hobbs Poly batting. It was sold to me as the batting people use all the time for donation quilts. I even told the people selling it that it was for preemie quilts. I have been splitting it but preemie quilts are very small. I think it would be very hard to split for a larger quilt. For very small baby quilts it is hard to use that thick a batting as the quilt becomes stiff. I just ordered Soft N Crafty toasty cotton batting to use for the smaller preemie quilts. It is on sale right now, 50% off and go to coupons and choose Sept60 for free shipping, and it is light weight and has a good drape unlike Warm and Natural or Hobby Poly bat.
