I have asked this same question.
was told they would most likely only pay for $2000 max.
unless you have receipts etc.
Fabric falls into one of those catogories like clothing
they pay you a flat amount
I have a business policy that covers my inventory(fabric, quilts etc) and I got it for that reason.
I don't support myself with quilting as a business but I do sell. Would hate to lose all my fabric and machines!
