My little sack person I always play as on LittleBIGPlanet 2. It's Ryoko from the anime series Tenchi Muyo! You can clearly see the types of clothing I used to make her. Took me a while to get the colors in the right spots, but it was all worth it.
I used a light blue sticker to color her hair, a white sticker for the kimono, black for the "waist thingy" (don't know what that's called, sorry T_T), a red sticker for the hands and legs, an orange sticker for her left sleeve, and a dark green sticker for her right sleeve. I basically used the basic shape stickers (square, circle, etc.) that are each one color.
The "coloring her outfit with stickers" part was long and tedious, lining up the stickers properly and making them the right size (not too little or too big).
I'm sorry to say but I haven't the slightest clue. It's been a while since I've last played LBP, so I can't remember where I obtained the stickers. Not to mention, college work is preventing me from playing video games. (T^T)
