Batting for hand quilting: I use and have used since I started quilted 46 plus years ago, Soft n Crafty hight or low loft polyester batting which is made by Fairfield and sold at JoAnn's in a bag. The quilts I did (see my avatar) are just as beautiful today as the day I made them. As a hand quilter who does NOT use a hoop or frame, I love my quilts to have a poof or puff to them and NOT be flat and this batting gives that to me. I have tried using a hoop and it caused havoc with my arms and shoulders. I now pin baste and then hand baste 2 - 3 inches apart top to bottom and cross wise and this works well but does take time but the reward is that I can take my works in progress with me to work on anywhere - quilt chapter meetings and a Happy Stitchers group that allows anything that uses a needed.
The ladies in my quilt chapter highly tout the warm and natural as THE BEST and that's all that they will use but they are machine quilters. At a recent guild meeting, the speaker is both a machine and hand quilter and she says warm and natural for machine quilting and the polyester battings for hand quilting which really surprised me.
My children and grandchildren tell me they love to cuddle up with their grammy quilts.
