Post-it notes

I saw this tutorial on youtube, it's very easy , very nice and I have no idea what am I gonna do with post it notes lol

But when you see such an easy and cute project you have to try it out..

After buying the post-it notes, cutting and scoring the card as seen in the tutorial..



Some stamping , layering and shading...



And a pen added...



I should get a smaller pen this one is only for the picture.



So what do you think? good project or useless one? I see it as cute.
