Will I lose your respect if I admit that as I painted and cut in the last few bits of 7's room, I had Dora the Explorer's theme song running through my head?
"I did it, I did it,... da da da do do da do do doo..."
Working a few hours on Saturday, a few more on Sunday, and a few more on Monday, I completely painted 7's room. We choose a nice, neutral greige for the background color.
(greige = grey + beige) The actual color choice is Benjamin Moore's Revere Pewter.
From the masses of
orange color swatches, 7 settled on two: Volcanic Blast and Dragon Fire, both by Behr.

Quote from 7:
"They're both cool colors and they both have cool names."
In preparation for painting the stripes, I needed a
temporary visual so that I could play with the height and width of the stripes. I went to Michael's and bought two shades of orange paper similar (but not exactly the same) as 7's color choices.
I decided on a 5" width for the center stripe and a 3" width for the outer stripes. After cutting them to size, I taped them to the wall to get a feel for where I wanted them. My first attempt was too high. But
since they were just taped in place, it was easy to relocate the stripes to a lower position.
Voila!
It looks good, right?The stripes --hereafter known as The Speed Stripe-- will go on these two walls.
I have something else planned for the loft bed wall.Tomorrow, while both kids are in school, I'll use John's laser level to tape off and prep for painting the stripes. However, I won't paint them because 7 is going to be involved in that process.
(You know. Ownership and all that.)
