Quilt appraised

For the first time I've had one of my quilts appraised professionally. There are no qualified appraisers to my knowledge here in England so sending Nostalgia to the World Quilt Show gave me that opportunity.
I an delighted! A professional has labeled the work as excellent heirloom quality in both construction and technique.
Now all I have to do is persuade my insurance company that my quilts are worth more than bedspreads, I'm hoping I can get them to apply valuations on a per square foot basis for my other show quality quilts as it isn't feasible to send all of them to the US for appraisal.
Now the aim is to make one of 'masterpiece' standard (I assume that's the top level). It doesn't matter if I never get there, it's the journey which matters.
(She also called me an International Award Winner, now that sound cool!LOLS)
