Of course it is normal. We all love fabric and the thought of ruining it is unbearable and we are sure we either won't like it or will ruin it. I have some fabric that I will most likely never cut, it is much too pretty and I keep saving it for that "special" project that hasn't come along yet. If I do ruin some fabric or find out there isn't enough of it, well, worse things have happened and 50 yrs. from now, nobody will know the difference.
