Does anyone know where to get blackout material, as cheaply as possible

[TheSkiingGardener]

I'm going to need about 20 square metres so cheap would be good.

TIA

ebay is your friend.

in north finchley, London N12 there is a curtain factory outlet- they do all sorts of curtain fabric a no more that 6.99 or 7.99 per metre. worth googling them.

Dunelm Mill's is £4.99 a metre (54" width)

Thanks for the tips. Ebay seems to be wiring out best so far. I can get it for about £3.60 a metre including shipping.

Although there is a new Dunelm Mill nearby and it is strangely tempting...

Dunelm also sell a good lining which is wadding backed so you don't need to interline..
