I was using MORNING GLORY 100% cotton punch needle batting (in the pink/clear plastic bag.) It can be quilted up to 5-6 inches apart and not come apart. When washed AFTER quilting, it shrinks up for a lovely heirloom look. Was great for hand or machine quilting. Got it @ Wal-Mart but they have discontinued it. I have called the company and it is sold at HOBBY LOBBY (we don't have those stores in Pacific NW ) in S. W., mid-west and eastern states! Will have to have AZ friend send me some....
