I just quilted a charity throw on my new longarm. Can't say the quilting is great yet, darn, but, I'll get there. What I don't get is why are my sides wavy when I put the binding on? Am I not pullting the binding tight enough? Do you think it might have something to do with a bit thicker batting? I'm pretty frustrated over it. Am hoping the recipient won't get too upset. Thanks so much for any advice you can give me.
