It was pretty easy and cute. Would you like to have a go? Here's how:
You will need:Felt (I used 3 different colours but you can use whatever you like)
embroidery thread, 2 little buttons, this pattern and a sharp needle!
Cut out your felt pieces.
I chose for the darker orange to be the outside so attached the flower and one button as marked on the pattern.
The other side looked like this (but it won't be seen so it doesn't matter):
Now layer the other main piece on the wrong side, lining up carefully and pin in place.
Using 3 of the 6 strands of the embroidery thread, blanket stitch around these two layers.
Now fold your middle section in half and pin in position where marked on the pattern.
Using the 3 strands of embroidery thread again, stitch along the pinned line to hold the "pages" in place.
You are going through 3 layers of felt here so you might find it easier to stab right through to the other side and pull the thread right through for each stitch, that way you get nice even stitches on both sides. I think this is a stab stitch but don't quote me!
