In this instructable, I'll show how I mounted some simple IKEA Lack shelves without any nails or drilling. You will require a corner so the shelf can be supported at 2 sides.
IKEA Lack shelves are great in that they are light so they can be added to your wall without much effort. But do keep in mind that you won't be able to hold a lot of weight, maybe 5lbs at most. I use it to put up some trinkets or figures. I wouldn't put glass or other valuable things that could break. Since I've put these up, they have never fallen down. It also depends on your wall... if they're dirty or really porous, they may not adhere well.

Step 1: Things You Needs
A corner is very important since it'll support the smaller IKEA Lack shelf at 2 sides. The longer or bigger Lack shelves probably will be too heavy and big.
The smaller LACK shelves are about $5 each.
You'll also need some large 3M Command adhesive strips. These are usually used to hang up picture frames. There is a side that you stick to the wall and another to the frame. They do a fantastic job with frames. I've had my pictures up for over 2 years and they have never fallen down.
We're going to use the same Command strips for adhering them to the wall.
Step 2: Command Strips
For one of the sides of the Lack shelf, it has a course wood side. In order for you to adhere the 3M command strips to it, you'll need to use some small nails.
Step 3: Command Strips
For the smooth side, you can just stick them on.
Step 4: Measure
Find out where you want to place the shelves. I usually leave a 12 inch gap between each shelf.
Step 5: Wall
Stick the other side of the 3M strips on the wall.
Stick the shelf to the wall and you're done. Make sure you push in firm.
