I agree totally. Since I haven't been quilting that long, I'm interested in making bed size quilts for my family, who all have queen or king sized beds.
I emailed Carrie Nelson who designs under the label of Miss Rosie's Quilts to ask about making one of her patterns a king size. She not only told me how to do it, she figured up the additional yardage for me. So, you might try emailing the designer for the assistance. Carrie was very accomodating and responding with a huge long email describing how to go about it. She was wonderful!!!
