INSOMNIA project... any ideas for a temporary mess on walls??? HELPPPP!!!!!?

[Louise K]

I've got an art project due in on friday... 5 days.. EEK! I've done everything towards the final outcome, and I've come up with a fantastic idea.. but it involves COVERING the walls of my dads spare room in black stuff, coming out of the bed and running up the walls, onto the ceiling and down across the floor...

Now obviously, he's not too keeno on that idea, so is there any materials I can use that won't stick permanently..? I've bought a ridiculous amount of black electrical tape (120m!) but im worried it won't really give the effect I'm after... scary, nightmareish-ness.

I've also thought of using wool, or cotton and blue-tacking it up.. but that's going to be a tad tedious...

I thought about liquid latex, if I could get it jet black.. and creating some mega drips in college but hmm.. i just don't know what's going to work Sad

any ideas will be hugely appreciated Cheesy

thanks
