Fortunately, I was in the sewing room when it happened, so frantically started grabbing stuff...it was a lot of fabric and quilting magazines that suffered the damage. My sewing room used to be a small beauty salon and has water pipes in there. My worry now is that the plumber will have to open up that wall :( (And that I will have to spend my tax refund to pay them, when I had MUCH better plans for it!!)
Will contact insurance company tomorrow.
