As far as I can see, unryu paper is the same as mulberry paper but with extra long fibers stuck in. (After treating with MC etc) will those fibers make a difference in the folding? Does unryu actually feel different from mulberry? I've also seen the sometimes those papers have btw of bark/mulch stuck in them, do I still have to worry about since I'm buying it from origami-shop, and the bark is only in unryu not meant for origami? I'm kind of drawn to the mulberry paper because it comes in a bigger size, but if you could let me know if there's some reason I should buy the thai unryu instead that would be awesome
