Mini photo album

When my friends came over for lunch last month, I taught them how to craft this mini photo album.

The size of this album is about 3"(7.5cm) X 2"(5cm), and it can include eight pieces of small pictures.

They don't usually craft something like me, but enjoyed crafting together as well as having lunch.
One of them asked me to teach them something once a month, then I am going to come up with some ideas and teach them something different every month.
The theme for next time is going to be how to make a handcurved eraser stamp.
