Arrange these as desired round the signature square, then sew together into a block. Repeat above steps seventy-nine more times. Don't think about it, just do it. Assemble quilt in 10 rows of 8 blocks each. Sashings can be added here, but remember that they will increase the finished dimensions of the quilt.
Borders are also optional.
Now, about those 960 extra pieces you have left over. If you don't want to do that much sewing, I'm sure just about any quilt guild would accept a donation.
