I want to put up curtains/blinds in our new home, but I don’t want to put holes in the walls just yet…?

Question by Porcelain Diana: I want to put up curtains/blinds in our new home, but I don't want to put holes in the walls just yet...?
My fiance and I just bought a beautiful house, and this is my first time ever decorating my own home. I want to put up nice curtains or blinds to block the bright sun in the morning. Is there any way NOT to put holes in the wall? I don't want to hire a professional b/c I really want to do it myself. Do you have any suggestions on easy installation without holes or damage to the wall? Thanks in advance!
