Explain this:
I'm adding borders on a quilt top. When I measured for the first border my numbers for the length were: Top: 89.25 Middle: 89 and Bottom: 89.25. I cut the borders at 89 and sewed them on. Then I measured the quilt for the second border and my measurements became: Top: 93.5 Middle: 94.5 Bottom: 93.5.
How did middle measurement become an inch larger than the others? The strips were all cut at the same width and I used the same seam allowance.
What should I cut these borders at? Use the middle measurement? Average?
