I love these cute tiny envelope books. I just don't know what to use them for...

What you'll need to make this cute little book:
- Some carton, preferably thick
- Paper glue
- Scissors
- Coin envelopes, either finished ones, a template or printed out to cut yourself
- Wrapping paper that goes with the colour of the envelopes
Start with the cover of the book. Measure how big the envelopes are, and add about 0,2 cm on each side. Draw the back piece and cut it out. Make one similar. Then draw one piece that's half the size of the two equal pieces. The width must be the same. Depending on how many envelopes you want in your book, you will need to equal pieces with the same width as the others, just very narrow (see pic).  
Glue each piece to the wrapping paper. Let it dry and cut them out. Now glue them on to the paper once again, on the other side. Make sure to keep about 0,1 mm space between the pieces, and glue them in the same order as over. Next, you let the pieces dry once more and cut out the full coherent cover (see pic). 
Now begin with the "pages", the envelopes. Cut off the closing flap, you don't need that one. You should use 4-8 envelopes. If you are making them yourself, fold and glue them like shown over.
Now glue your envelopes on top of each other. Make sure you only glue a small strip in the middle of the envelopes so that you're able to open the envelope book.
Glue the back of the stack of envelopes and attach it to the cover. Then glue the front of the stack and fold the cover to finish the book.
I made many of these, but I don't quite know what to use them for! Any ideas? Maybe fill with encouraging words? :)
 
Now this is what I call easy and decorative!

These are envelopes made of magazine paper, but you can also use wrapping paper for presents. The only things you need to make your own envelopes, are a template (either print one out from the internet, or make your own - that's what I did. You may use an envelope you already have as well :) ), scissors, a pen, some glue and of couse, paper of any kind.
Now you just lay your template on the paper you wish to use,
and you draw a line around it with a pen. Then you cut it out and you glue three
of the flaps on to each other.

You're done! Now wasn't that easy?!
