Shoebox organizing idea : Another recycling project

I always have a problem in organizing. Now a days, I really wanted to reduce clutter. So, I was brainstorming for ideas.

My family's wardrobe is really a problem. Yeah... Not any more. 
Because, I found out clothes can be filed. 
I found that people folding and filing clothes in the chest drawers.
I have to tell you all.. It is really great and I have a lot of space now. Better yet, I don't have to mess up to find things.
I had few Ikea organizers, which were under utilised. So, I used them to file T-shirts and pants. 
When the boxes are all used, instead of going to Ikea, I used some shoe boxes, which happened to be in the home.

 Those are shorts, filed in the box.

Now look at the T-shirts...

This is really great upcycling (or is it recycling?) project. I didn't even bother to pretty up the boxes. That can be done later. Right now, it is fine. Sure, I will find some old magazine papers or wrinkled gift wraps or used gift bags to line the boxes.  
If you have any organising tips, please, please  share with me. Need more ideas to tame the papers, like important documents, bills....
