It was the guest on the Fons and Porter show that told about this story. She found out the hard way. Apparently it gummed up her plumbing and cost her a fortune to get it fixed.
Another hint was to put a bunch of little pieces of the stabilizer that you had cut off from your project and were too small to use anywhere else into this water. Stir until it is cloudy. Put in fridge (it molds if you don't). Then you can use a paint brush and paint this liquid stabilizer onto the back of your fabric and let dry.
I don't use this stuff so don't know any more than I'm telling now. I just thought it was kind of interesting.
