Nice, I don't think I can ever finish any of those larger pieces.
If anyone lives in NYC, there are tons of stores in chinatown (Elizabeth St & Canal St) or in Brooklyn chinatown (8th Ave & around 50-60th streets). They have tons of different sized origami papers in nice patterns as well as many kits for creatures/cartoon characters, star paper, turtle paper and more. If anyone's up to a personal swap, I can get you stuff. Everything's really cheap too, from 50 cents to $1 a package and ~$3-$10 a kit.
Hey hey hey! Don't forget Main St. in Queens! We have our own Chinatown too!
