So I put some stripes on my "hallway" walls and I like it a lot. I started late on Sunday and put the painters tape in the appropriate positions (not easy without a level to use and a long weekend of too much fun under my belt). I measured the wall height from the top of the floor moldings to the ceiling. I knew I wanted wide stripes and wanted to maintain more of the lighter wall color ( i.e. have one more of the lighter stripe) so I took the height and then divided by 10 (5 stripes x 2). I then measured starting from the top and marked my way down and then got to taping.
I will say I am pretty pleased with the results, there are some spots I need to touch up because when you have old plaster walls you quickly find they are not perfectly flat... there is a lot of variation, but that's what you get when you live in an old house... lots of variation. :)
The blue tape in the middle is to ensure I didn't completely eff it up and paint the wrong stripe. I would recommend it if anyone is thinking about doing this in their home.
The picture isn't great lighting but you get the idea.
