synthetic

oooh
You can get WAWA up to 22" on a weft adn it can be ironed

American Dream sells there therm on a weft in 18, 36 and 60" lengths?

Of course if its for clip ins synth is very affordable.  You could get PH in straight and also in curly.  And switch them out.  PH wefts come up to 40" long (same price from 24" to 40").

For WAWA try vixenwigs on ebay

For American dream one of the other girls here would have to give you the phone number, no website/web ordering last I'd heard.

for PH

the info on weft prices is under wefts (on the left menu) the hair to see the colors is under synthetic hair, kanekalon monofibre.  You'll want the natural colorsin all likelihood.  But the fancy colors are awesome if that's your thing.
