Problems focussing on crosscuts

[cornucopia]

Hello everyone,

I wondered if any of you could point me to a good source/problems focussing on crosscuts. I tend to avoid them because I'm not at ease with the possible variations and as such I would like to train myself on the subject. Is the Crosscut workshop ok? Or are other sources available?

Thanks!

Thank you very much! I'll be sure to have a look at the book you suggested.
