LOTS of Cotton-ish Bed Sheets Needed

[ac...@provide.net]

Hot request...
I'm seeking a LOT of old Queen/King (or twin.. any kind) white
cotton-ish bed sheets (not clear plastic).

.. Anyone have old white bed sheets they're ready to dump?
.. Any known recycle sources for lots and lots of old white bed sheets?
(I'm already looking at PTO Thrift Store, Goodwill,
AARecycle/reuse, etc...)

I'm in reconstruction, and will soon need to have utility workers
traverse non-disclosure sensitive areas and paths within my home-shop.
I need to
-- segment/hide large open hall areas and basement areas with "curtains"
to reduce dust spread and visibility
-- cover an entire lab full of stacks of little static-sensitive parts
and things
-- hide from sight many non-disclosure items from utility workers'
prying
eyes while escorting them in and out.

I'm avoiding plastic "drop cloths" due to static concerns and
non-opacity.
The cost of the needed qua=ntity of brand new thick painter's canvas
drops
(or the number of NEW bed sheets) would greatly affect project cost.

So I'm seeking simpler/cheaper alternatives. (grin)
I estimate I'll need at least a dozen (or more) king/queen bed sheets
for this overall, but obtaining at least a few would get me started.

If anyone has big old bed sheets and they're looking for an
excuse to replace them, please contact me directly asap!

Thanks!
