I bought some warm and natural to use for a baby quilt. I washed my fabric. I was going to wash the batting, but it said not to. It says on the package it will shrink 3 %. Since I have not used it before, what will it do to my quilt when it is washed? Will it cause the quilt to buckle? Not sure I want to use it if it will. Would appreciate any help I can get. I am new to quilting and really don't know the in's and outs of how and what to use. Thanks so much.
