There are so many battings available, it can be hard to choose which batting to use in a quilt.
Some questions to consider are : How will the quilt be used and washed? Is it a childs quilt? Is it a wallhanging? Is it for a large bed? Or is it a cuddle quilt on the couch? Will the weight of the final product matter? Do you sleep hot or cold? Do you want shrinkage (for the antique-y crinkled look) or no-shrinkage?
Battings I have on hand, and available for your quilts:
Hobbs 80-20 cotton-polyester blend
Warm and Natural 100% cotton
100% wool--washable in cool water and cool dry
Quilters Dream 100% Cotton Deluxe weight, no scrim
I can order in king size battings if needed, as well.
The availability of battings may vary over time.
