Did you save the receipts from the fabric? And if you had it LA,d did you get and save the receipt? If you quilted it yourself, did you keep track of the hours and expense of thread, batting, etc.? All of this along with a pic of the quilt can be kept as a "proof of value" for homeowners or renters insurance. I would offer them the information (or keep it for them) so they could have the value added to their insurance policy. I know it's uncomfortable to tell someone the value of a gifted quilt but think of it this way, if you had purchased something off the bridal registry they would know the cost.
