I got my haircut on Saturday; it was in desperate need of a trim. Brian also needed to be cleaned up, so Monday morning I trimmed up his hair while he watched tv and ate fruit puffs. After that, I guess I was feeling confident and decide to do Elizabeth's hair. She's also needed it for quite a while. But I've been too nervous to take her to Supercuts - for fear they'd really mess it up - and to cheap to take her to my hairdresser ... so I did it myself. Clearly, that was the most logical compromise, right?
The conclusion: It's shorter than I intended, but also not as bad as I expected. (Curly hair is very forgiving!) I will likely cut her hair again in the future, though maybe after reading up a little to get some technique.
