I have found that sometimes the seams of the top pull a little bit apart as I attach the borders. I now pin at each seam to hold them together. Guess I tend to pull a little bit too much.

This is what I do, not just measuring in the center. I don't usually have a problem with wavy borders that way.

I measure the three places-average, I cut length of grain iron in half to mark center, pin the middle-then the two ends, then pin the middle of the half and ease it with pinning, use a walking foot.

I usually dont have any problems and my quilts are square but now that I say that the next border I do will be a mess!

Also I put the fabric that stretches the most on top! It seems to lay flater that way :D

Great posts---thanks!

Thanks. I've been ironing, yes. But didn't "think" I was stretching.

I'm also wondering if measuring from the backside, rather than the front, is giving me the wrong measurement.

Thanks for your thoughts.

Yes, I'll watch that! Thanks!

Ha! I hope not! I'll try the walking foot next time. I usually don't use it though. Could be part of the problem.

Thanks!!

Thanks!!

Stopped at the Bernina Sewing Center yesterday to discuss obtaining the new walking foot. Learned several things about a walking foot. They have more uses that quilting in the ditch and sewing binding. The best use, and I found this interesting, because I,too, have this problem, wavy borders, one seam always sews longer than the other, puckering seams and the list goes on. That's why is it also referred as an evenfeed foot. I'm not sewing on a project right now, but I going to try it next time. Due to budget, I put off purchasing the walking foot until next week. So, do as suggested, take 3 measurements and averaging, and sewing your border with the walking foot. Good luck.
