Well, to put it short and sweet, have you tried some of the dozens and dozens of truck breakers in the greater Moscow area?
REading this post, I think the OP is looking for Tarpaulins, old rope and sheet type, Not curtains. 
Best bet is to try trailer repair yards.
I only know of one though Crusely Trailer Engineering Ltd which is in Thurrock.
Sure there are more out there though.
I would ask Bewick or some of the others on the Old Timers Forum & the ‘Roping and Sheeting’ thread
I don’t think that is what she meant, but I get a strong familiar scent coming off this thread, the one you smell in the countryside in spring, when fertilizing takes place 
I just need to find out where could I get a tarpaulin itself, and the shipping is not exactly what I’ve asked about
The above companies make new tarpaulins, could be possible they have off-cuts of old sheets beyond economic repair. At £4/Kg it’ll still be quite expensive to send. An 10m long rolled up sheet weighs over 50kg. Good luck!

You think Ms Marcarena is shaking her bootie at you?

I think Ms Mozzarella usually goes by Desmond or in some circles, “Karla” 
Hi Liliya,
here are some firms from my area (Liverpool and North Wales) for you to contact:
…be sure to mention the expression we use -" off-cuts" - and they will know exactly what your enquiry is about. 
Good Luck 
I can get pallets of Curtains that have been removed.
Don’t mean to hijack the thread but I’m looking for a bit of old tarpaulin or curtain, just enough to cover a pallet of coal on my mooring, so if anyone has some in the Rugby/Coventry area please let me know. I’m too mean to hand over any cash money for it but I can collect it or I’ll take you and your friends/family out for a ride out on the boat as payment if you can deliver it to CV23 0PT on a Saturday/Sunday morning (nearby Rose Narrowboats charge £180 to hire out their rather inferior day boat for 6 hours).

Was it this one

If Harry Monk is being serious I have a plastic tarp around 10ft.square which I used on my shed roof when the felt had deteriorated.I’m not going down Rugby way but I could make a parcel of it to ship down.

I am being serious, I do need a bit of tarp or curtain but because my boat doesn’t have a postal address it’s something I’d have to collect locally, but many thanks for the kind offer.

Have you received a pm from the OP yet? Considering she has logged on after your post.
