Please note that electric cutters will not cut the full length of a staight knife cutter blade, nor half the diameter of rotary knive blades. You have to allow for a header between the top layer of fabric and the top of the knife. Otherwise the fabric can jam in the knife. Allow about 15% or more knife dimension to cut your fabric layers height.
As an avid crafter who use material both for sewing projects as well as for craft, I know how time consuming cutting fabric for panels and shapes can be.
