Firstly you will need to choose the cutter you require:
What types of projects are you creating? Appliqué? Piecing?
How often are you sewing/quilting?
Where do you work?
Do you have restricted wrist mobility or grip ?
Do you need your fabric cutter to be easy to lift and move?
Each cutter has at least one die & mat to get you started. This is different with each cutter, so whichever cutter you purchase you will have your first project to hand.
Investment in at least one strip cutter & mat is our recommendation as well as a Qube Mix & Match Set if you are a piecer. The Ultimate Cutting Set is excellent value, it has the 8" Mix & Match Qube included as well as a 2½" Strip cutter.
