I believe Sharon Schamber discusses that in one of her free videos...I can't exactly recall, but she shows how it gets smaller when you spray it with starch. Frankly, I don't see what difference it makes, unless you plan to spray starch while the freezer paper is on...then perhaps. Does anyone want to be a guinea pig and set up an experiment? it would be a fun one, and you could post photos to show the difference...might me a good lesson for everyone!
