Under the guidance of a LQS teacher I just finished a medallion quilt with over 1500 pieces. We used every die in the CUBE and I used my Accuquilt Go cutter. The pieces fit together so well! Our teacher demonstrated how to subcut and accordian fold fabric with very little waste...probably less than I would have wasted with mistakes using my rulers and rotary cutter. As a relatively new quilter, the cutting accuracy helped make up for my sewing skill level.
