I first cosplay was in Amecon 2007, where I cosplayed Jaden Yuki/Juki Judai from Yugioh GX. I even made a plushie for this cosplay too, "Winged Kuriboh" in which in my case, greatest Achievement.
In Amecon 2008, I've also made another cosplay. A dungeoneer from the Kids gameshow "Knightmare".
In Ayacon 2009, I've on the biggest project by making a mecha cosplay.
