I saw your other thread, but I hadn't thought of anything useful yet !
I think your best bet is going to be to sew it - piece two different colours together.
I think this will actually take less time than painting it - for that to look good, you'd need to paint down to the roots.
With pieces, you can be very systematic and cut out a whole bunch and sew into rows and then sew the rows together - it goes pretty fast, and I'm guessing faster than it would take to hand-paint it all.
If you do piece it together, you might consider bagging out the pelts very slightly for a more realistic look, you could stabilise the lines with twill-tape and it would be a bit like "gathering" - this would make even pure white look visually interesting. You could do this very quickly by pinning a horizontal row - pinning at each bottom corner of each "pelt" to a line of twill tape and holding it as you sewed it.
Also, I'm not sure if it's the same with faux-fur because of the woven backing, but real fur is whip-stitched or machine zig-zagged together (there are special machines for this, but can be done on a home machine), with edges butted up against each other, or against "filler" leather in lesser quality garments.
You can buy squirrel pelts, even the kind you need - but they'd be pretty expensive to line a cloak with. You'd be looking for "Russian Grey Squirrel". You might
be able to find a faux version - but I don't know where you'd look. You could probably find faux sable pretty easily since it's still a very common and desirable fur.
They have squirrel pelts here : http://www.chichesterinc.com/Squirrels.htm
, you might be able to negotiate a bulk purchase deal, but it would likely still be very expensive - the #2s are still $20/e - they might have something more suitable in their large catalogue, though - I've never bought from them before, so I'm not sure.
Glacier furs is having a sale on sable pelts : http://www.glacierwear.com/index.php...her/sable.html
, but they're still expensive at $90 each.
