Introducing the new MS+ Fabrique Pieced Shapes Design Card. So ... what IS MS+, you ask? Let us tell you! It's a Mirroring, Shadowing PLUS Speed upgrade. The MS+ cards will install the Speed Boost update on your Making Memories Slice so it will be faster regardless of the Design Card you use. The Mirroring will only work on the MS+ Design Cards. Mirroring allows you to flip an image making embossing and debossing simple. The Making Memories Slice Design Card is designed for use with the Making Memories Slice Fabrique Fabric Cutter.
