Thank you so much for this post! I sometimes quilt on my sewing machine, but larger quilts generally go to my LAQ. I'm so fortunate to have someone like you, who will give me the info I need to improve the quality of my tops. I've become a pre-washer whenever possible, and knowing it helps my borders lay flat will push me more in that direction.
I'd love to see additional tips from longarmers along these lines!
Thanks again!
