Or try out a test pattern… 
Last night was the beginning of real painting. In fact, but day’s end today we should have quite a lot done. Master bedroom, kid’s bedrooms and kid’s bathroom should be all but done.
Kristin’s room? Looks great doesn’t it? Can’t wait to get the glow-in-the-dark paint flecks for her ceiling. Should look really, really cool!
Test patterns are bonus room over the garage and the back wall of the living room. Bear in mind that these photos just don’t do this justice.
