Learning the first 20 Hiragana

last night and today I have been practising and learning the first 20 kana in the hiragana chart!!

I have pretty much memorised them all though I do have to think about "ki" and ke" because I keep thinking that the kana for "ki" should be the kana for "ke" and the kana for "ke" should be the kana for "ki". I'm not sure why my self ether. So the next 10 I need to learn is the "na" and "ha" column. Yay, nearly half way there!!
