Rotary cutters cut all fabric kinds fast and easily, up to six or eight layers at a time, without altering pattern cutting lines. They are especially appreciated by volume sewers and arthritis patients because the blade does all of the work while you grip the handle and apply light pressure. Some kinds can be modified to control the amount of pressure applied, allowing for fabric weight variation.
