Improving your work: proofreading

I'd like to ask for your thoughts on how you proofread something when you finish your first draft of a piece of writing.
Here are some things I do:

• go away and leave it for several hours, or overnight and then read it again
• read it aloud
• print it out (if it was on the computer), take the printed version away from my desk and read it in another place
• go for a walk and read it aloud when I get back

This was looking at the macro process (thinking about the overall plan, logic, completeness and whether it makes sense). Now what about the fine detail, the micro process? If you're writing in a second language how do you go about checking something is correct? Here are some ideas:

• read it aloud
• check bits that seem wrong in a grammar book/ dictionary/ against a model
• ask somebody for help with a problem bit
• check to make sure you haven't made your 'favourite' (most frequent) mistakes

It would be great to get some comments from you about what processes you go through, in your own language and in a foreign language. Looking forward to your comments!
