Onebyone, you are absolutely right! We could not believe some of the things that WERE included in our policy and some that WEREN'T. For instance, $200,000 for a flooded basement. Since we only use it for storage and because of our location (50 feet up a hill with a walk out to the back yard) it would have to be the second coming for our basement to fill with water. (We lowered that amount to a much more realistic number)
But back on topic, I would guestimate that my stash is around $5k. My machines are not that expensive but I would hate to lose the fabric and patterns that I have accumulated. And I have been quilting for less than 10 years. I like the idea of weighing the fabric. It would probably give a more accurate number.
