When I was researching some interesting color tools (that let you experiment with various paint colors and ultimately pick the right colors before painting each of your rooms) I came across this:

Masking tape... "although it isn't as popular as duct tape, most homes have at least one or two rolls around the house." Source

Painter's tape... "has light, or weak, adhesive. The paper backing of the tape is easy to tear." Source

In my opinion, blue painter's tape is utterly indespensible around the house! It's great because painter's tape sticks to the surface, but leaves no sticky residue when it is removed.

Alright, here we go...
