Studio / Still Life Backdrops

What is the best thing to use for a white or black or coloured background for studio work. I am talking at home here on a table top or similar for still life. I want to use natural light with a bit of infill and the largest item is likely to be a guitar or similar sized object.

So, paper or cloth? And where can I source such materials?

White plastic sheeting, made for protecting from decorating splashes. Might need several layers as it is thin but you can also defuse light through it as in a light tent. Last one I got was from the Pound shop.

Black. Black velvet is good.
Try the black weed control fabric sold in garden centres, much cheaper. Saw a whole Santas grotto made of the stuff, did a good job too. Can of course be pinned to frames or draped over whatever. Last I got was from one of those cheap houswares shops, £2.99 for 1x10m roll.

Any dealer should be able to help, and a copy of Amateur Photographer will offer you a variety of alternatives.

Calumet do a good range of papers and cloths as well as support systems.

Thank you all for the ideas, the calumet wewbsite looks like it has all I need.
