Is there by any chance a deck of sentences that attempts to give (about) 3 sentences for each kanji in the "reference" section of KO2001? These are the kanji that don't have any sentences. If this doesn't exist, would enough people be interested to make it a community project?

Kanji in Context Workbook Vol.2 should do the trick...

KiC's order is different from KO if you go that route. So you'd need vol 1. just in case.

Also, keep in mind that KiC does *not* have sentences for every vocab word like KO does for the first 1110 kanji, either. (Supposedly the 3rd book is coming soon?)

You can always just use an online dictionary like yahoo.co.jp, or ALC. It's quick and dirty, but it saves a lot of typing time. (It also gives you the freedom to pick shorter sentences.)

I like the example sentences in Yahoo's JP-EN dictionaries, because you have 2 to choose from, and you usually get multiple examples for each definition. If you're going monolingual, you can always just skip the EN translation.

I've been using http://tatoeba.org for words that aren't in KO2001's sentences.
