Hi,
Welcome to the board! I love your quilt-- great new line of quilting fabrics!
My quilts get pretty crinkly. I use Warm and Natural batting and 100% cotton fabrics and thread. Then I wash warm and machine dry. That's my only formula!
If you want to see how they turn out, you can look at my album in my profile. Plenty of crinkles, especially the Bento Box....
