My quilting teacher taught us to measure (for our border) in 3 places across the quilt: the middle and each end. And then cut your border to the average.
Ex: Your measurements come to 34 5/8, 34 1/4,and 34 3/8 inches . Add those up. Divide by 3. That's your average. (To anyone who has forgotten how to convert fractions to decimals, the "line" in the fraction means "divided by". I don't mean to "talk down" to anyone, but since math is NOT my strong suit, I sometimes need simple reminders from 4th grade. LOL)
In this case, total is 103. 103/3 =34.33. I round to the nearest 1/2 inch if the answer is "weird" like that (great math word, huh?). So, 34.5 is the length of the border you'd cut in my example.
It's easy to forget that the layers of the quilt don't all get "chomped on" by the feed dogs at the same rate. Hence, the waviness. Believe me, everyone's done it.
