This is very easy and it's free if you have all the supplies :)
When you have all the supplies, you can start. Clean the jars and containers if they aren't allready. Also if there are labels on it, get rid of them.
Now cut out pictures out of magazines. It can be everything you like for example; clothes, make-up, models, animals etc. Just make sure you have more then enough.
When you have enough pictures, start pasting them on the container or jar you want. Paste them in any way you want.
Now you can fill them :)
