Thank you for all of your kind comments. When I turned in the quilt to Martelli Enterprises they gave me two packages of 5 replacement rotary butter blades for a total of 10 blades. Bingo! I did not expect that. I was so excited as I had planned to buy their erognomically designed cutter while I was there. Talk about excited! All their fabrics were $5 a yard and all notions were 25% off. It was well worth my time and effort.
