Book binding

I always wanted to bind a journal by myself and I found a "recipe" to do a little one within 10 minutes! So I gave it a try on saturday. And indeed it was pretty easy and quick without having any experience and I'm pretty proud how I managed it! I used Fabriano hot pressed watercolour paper and I'm curious how I go along with it.
Here how the front and back cover look like.

(I think would be also a nice gift for someone to fill it himself.)
