Hi Jess. If you need paint & paper there is a great place in Wallasey that sells donated paint/paper at dirt cheap prices. (£1 for 2.5 ltr!)
It`s based at: The Sandon Building, Falkland Rd, Wallasey, CH448ER.
The chap to see is Mr Jim O`Neil. Contact him by e-mail firstname.lastname@example.org or Tel: 0151 639 2121.
I gave them about 50 litres of mully & gloss not long ago, and they had 2 steel containers with lots of good gear just waiting to sell. Well worth visiting. Good luck.
