Starched fabric can attract a bug called silver fish and other moths I believe. It's especially true if you were to starch your fabric then store it. Starch can also yellow your fabric overtime. It's a great product to use when quilting though, go right ahead, but just wash your quilt when you are done.
I always buy Niagra starch just because I always buy my products like that at Walmart, and that is what they carry. I have never had any problems with it, and works great.
