Just went to crafty site to see the " updated" version of the pattern. It states sizes for up to double......ok, but for anything larger than kiddie - original version - those strip panels, in my mind, would need some anchoring along the way or I would imagine the "lumping" when washed and handled would be disastrous. I wonder if the new pattern addresses that......if anyone has it can you tell us? I think if I were to go bigger, I would channel quilt those panels as I added them....JMHO
