Sometimes when measurements don't agree, you might find that there are 1 or 2 seam allowances that are a bit off and can be corrected easily.
Remember to press, go up and down with your iron. It is easy to distort the fabric with the "scrubbing" motion of regular ironing. Also, I have noticed that when MY DH helps with measurements, he actually pulls on the quilt, distorting it by an inch or more on a bed sized quilt. It is better to measure on a flat surface (I used the floor when I was younger.) Sometimes I "borrow" the use of a table at a local church or senior center. Sometimes I measure a portion on my dining table, place a pin then measure the rest. If I am simply trying to see if the sides agree, I fold the quilt in half each way. No measuring, I can eyeball it.

I think you're right to just get it done and get onto another one. I just worked on one that someone made 60 to 80 yrs ago and she used the flimsiest fabric and I ended up having to use my sewing machine on points to keep it so it would be useable. I got it done, and the binding I just made very,very long and started sewing it on. It looks pretty doggone good!ha.
