Why buy Post-It Notes?

When ever I get done with a class or get assignments back I feel bad throwing away or recycling a half used paper.

So I figured that I would just cut off the unused part and save it for when I just need a little something to write on.

Now I can recycle the written on part.

I usually keep all my extra in a stack but I had a lot of little ones so I cut all to the same size and made a little booklet.

This is an easy way to reduce wasting thing and to save money by not buying Post-its!
