This lovely, childish Hiragana (and Katakana) chart is now a part of my room. Actually, I bought two of these at the 100 yen store (did I ever post about how fabulous those shops are?!) and put one in my room and the other one in the... bathroom.
I know all my kana by now, but once in a while I still confuse some similar characters. It drives me insane, so those colorful charts have been quite helpful memorizing everything, and even learning new words. Fun, fun!!!
