Leather Bookmark

I made this leather bookmark in grade seven during Industrial Arts class. That year, I believe Industrial Arts had three modules: power mechanics, ceramics, and leatherworking. I don't remember all the stages of the process I went through to create the bookmark; I imagine I cured the raw leather first somehow, and I seem to remember immersing the strip in water for a while. Then I used a small mallet and a number of...I guess I'll call them chisels...to beat the design into the leather. This is the end result. I think it's supposed to be some kind of flower.
