While your customer wanted simple, I am sorry to say that she may have a problem with the batting bunching up in one or all of those long borders with no quilting going a span of 60" and 50" even if it is a channel only 3" wide. The problem probably won't manifest itself until after the quilt is washed several times.

You are doing this as a business, so you really are responsible for educating your customers and yourself. Sometimes what they want is just not possible because of the nature of the batting. One dissatisfied customer, even if the dissatisfaction occurs a year after you quilted, could cost you a lot of bad word of mouth advertising.

About the only time you can get away with long channels of quilting with no cross wise is very tightly space lines (1/2" or less) apart. Just sayin.
