Is this the quilt?
If so - it looks like six different fabrics were used for the blades - five of them were used seven times and one of them was used only six times.
I think if one used a different multiple of fabrics like five fabrics repeated 8 times for a total of 40 blades - it would seem like it "should" work out.
