We have zipped topaz into the darlex lotus sack with her arms pinned behind her back in an inner sleeve. We are confident that topaz will be unable to escape but we are amazed as, after some struggling, her fingers appear out of the neck of the sack. we tie her up again, this time padlocking the zip of the sack. Still she manages to escape. for the third escape attempt we use two leather straps to tightly hold her upper body in place. Surely she will not be able to escape now?
