I taped the drywall in my bathroom today. Everyone had been shaking their heads and saying, dubiously, "Taping is kind of... an art," and as a result I was very intimidated to try it. But it's not so bad, really. That probably has to do with my expectations for the quality of the result, which are low, and my trepidation, which was extremely high. But it looks fine, and it seems possible to fix the spots that don't look so great with another little layer of joint compound.
For those who don't know, joint compound comes in a big tub, and it's this goopy white stuff that's about the consistency of toothpaste. You can sort of smear it around on the walls, put some tape into it, and make a flat surface by going over the whole mess with a flat scraper. You end up with a lot of joint compound on yourself, but in the process you can fill in little holes or dents or seams and when you paint over the whole thing it just looks flat and smooth. That's what I'll be doing later this afternoon. (I've decided to ignore my home depot book that says to let the junk dry overnight. That strikes me as silly.)
