Repair Drywall Cracks
Most of my learning how to do it drywall joints from a few years ago have cracked (too much compound, I now know).
Can I just scrape out a little bigger crevice in each one, patch, sand and repaint?

Exactly what did you repair to start with?
Generally a crack in drywall needs to be taped and finished. Joint compound is prone to crack as it dries if it is applied to heavy but shouldn't crack later if it didn't crack when it dried.

It wasn't repairing -- it was new drywall work. I'd never done it before but I thought since I'd watched all those DIY shows, I would give it a try.
I applied too much compound, didn't wait long enough for each coat to dry and ended up with hairline cracks at just about every joint. The cracks appeared after a few days or weeks (after I had already painted).

What type of tape did you use?
The 'sticky' mesh tape is prone to crack. When you use it, it's best to use a setting compound over it [dries harder] Paper tape gives the best results.
Provided you don't hurt the tape in the process, you can scrape out the cracks and remud, with some luck, it will be ok.

I used the paper tape but I just did a bad job :-) Plus, we're in an old house here and things still tend to move around a bit from season to season.
Thanks for the help mark.
