What a horrible shame. It's bad enough to have something like that happen to your things when it is in your own home, but to have it happen because of someone elses carelessness. That is just not right. :evil: Renters insurance is a great idea, when we rented we always had it, thankfully never needed it......but it was there just in case.
Hope you are up and running (sewing) again real soon. Good luck.
