How I store my postcards

In 2013 I haven't made even a stitch. Really. Shame on me=( I was busy storing my postcards which I've received. I'm taking part in Postcrossing project and it's really great! The idea is that if you send a postcard, you will receive one back from a random Postcrosser from somewhere in the world. I like to receive real mail=) I've been a postcrosser for 600 days and have received more than 200 postcards. One day I realized that they must be organized. And on the 1st January I started doing it. I thought I'd go mad of cutting paper=) But now it's over.
