MS Paint is the worst PoS ever.Everything is on one layer,you can't smudge,add C4Ds,and only have default brushes.That is pretty much all you can do in it,so don't feel bad.If you can get Photoshop,i would recommend Paint.NET where you can have multiple layers,add C4Ds,download nice filters,etc.It's not as advanced as Photoshop but it's 10x more advanced then MSPaint
