Something a bit different. I was looking at redecorating my son's bedroom last year and contacted http://www.graffiti4hire.co.uk
for a quote which came back as £295 + £80 travel expenses for one wall. Just received an e-mail saying this is now £145 all-in. Unfortunately, my wife has other plans now (involving en-suite bathrooms £££) but I thought this was a good price for a bit of individual artwork.
