I ordered 2 Hobbs 80/20 Battings today. I usually use Hobbs Polydown batting --or I use 100% cotton batting if I want the quilt to shrink up and have that old-fashioned look to it. I am not familiar with 80\20 batting except it sounds like a lot of people use it. What would be the advantages of using it instead of the Hobbs Polydown? I quilt for customers and almost all my customers want the Hobbs Polydown --or they are precise about wanting 100% cotton. I'm wondering if I should add the 80\20 batting as an option for my customers but I need some guidelines as to when exactly to use the 80\20 and why would I use that instead of 100% cotton or Hobbs Polydown? I would love to hear some conversation on all this. Thanks.
