Although I do now have a sofa (see archives), I still can't see any
rulebooks under it. Just some fluff.

Will that do?

Can you re-arrange the fluff to make some new rules?

Hang on, I'll have a look.

No, sorry, . It's all carpet-coloured. It might work if I used a
contrasting surface...

Try putting your rules through a Dyson. It really mixes up the
play somewhat
