I feel like I've seen posts about this, but I couldn't find any topics on it.

How do you study kanji after completing Core 2k6k? I finished RTK a long time ago, but stopped doing it when I started the Core deck. My speaking skills are pretty good, since I use Japanese everyday, but I've never written anything after RTK.

I want to learn to write Japanese by hand. (I also feel like I'm confusing kanji I shouldn't and I'm sure writing will help reading and everything else too.)

Here are some methods I've thought of:

1) Do RTK again, but with Japanese keywords.

2) Do Core again with i+1 production cards. Front of the card is a sentence in hiragana and you write the whole thing by hand with kanji.

3) Do Massive-Context Cloze Deletion (MCD), which is cloze deleting one kanji in a sentence. Look at ajatt's examples here.

4) Do your own sentence/vocab deck and do production cards (hiragana–>kanji).

What do you think? How did you do it?
