Well! I finally found a book I've been looking for for over a decade!

The first time I posted this somebody suggested The Worst Witch, which really annoyed me, but it turns out to be Three Little Witches by Debra Hess. A book series that is very out of print, impossible to buy anywhere, and exactly two books in the series available at Archive.org.

But you know what? It holds up better than it has any right to! I was very pleasantly surprised. (Now I want other people to read these two available books so I'm no longer the only person in the universe who has.)
