Cool things to make out of cardboard for preschooler to play with

[YouCanDoItYesYouCan]

I have 2 quite big bits of cardboard (perhaps about 2x2 sq metres) that seem too inviting to put in the recycling straight away. I think it would be fun to make something out of them for DD (just under 3) to play with. Does anyone have any ideas?

That has just got to be a house or a den or a castle surely!

Let them eat sandwiches in there and take drinks in and a torch, put a table cloth or sheet over the top and leave it in the corner of the living room.

Or alternatively life size cut outs of him / you / your dp for him to decorate, dress up etc?

Castle.
tractor
bus
Tardis
Puppet theatre

ooh there is soo much fun to be had with two boxes.

Great ideas, thank you all. Liking the idea of a castle, especially as we've been reading Zog recently. Tardis would also be cool. Or cut outs of DD and she draws the hair on etc. Oooh, too many good choices!

You can do the life-size cut-out thing with lining paper too :)
