Where do you go get materials from?
Nottinghack will eventually have some baseline standard pieces, of ply and acrylic, in the space for sale. However for other materials you can buy them from a variety of places. This is a list to investigate places to buy from; many stocks and prices change over time.
Plastic and Wood
|Trent Plastics||http://www.trentplastics.co.uk||Acrylic, various colours/sizes, cut from 1500x1500 down to size||3-5 working days, cost based on weight, Monday - Friday delivery|

The hackspace has some standard A4 card in the craft areas, which would work fine.
