Step 1: Solve 90% of a 37x84 rectangle, then wonder why there's so much space left over and not enough pieces to fill it (37x84 = 3108, which is slightly overshooting the octominoes' 2952+6 total area.)
Step 2: Despair for a little bit. Even with a physical set of pieces I find ways to screw things up.
Step 3: Salvage a nice big chunk from the starting corner of the failed solution (the corner where all the scariest, hardest to work with pieces live), and use this as the basis for a new rectangle with the correct dimensions this time...
