Donating Paper Crafting Materials in the UK?

I have an incredible amount of paper crafting materials, ranging from stamps both wooden and acrylic, ink blocks, embellishments, actual cards and envelopes, paper plain and patterned both 12" and smaller for scrapping and card making. I no longer craft to the same extent and would like to donate to a worthwhile cause. At a guess I would say at new the materials could be valued at around £2k+. Please could somebody put me in contact with an organisation that could make good use of the above. I live near to Melton Mowbray so somewhere within Leicestershire or Nottinghamshire would be convenient.
