It was quite the process - not easy by any stretch of the imagination. As you saw here I started with this:
I was originally going to four graduated color stripes with no white in between. However, once I got the first stripe up and measured they were going to be really big stripes and I didn't think I would like the way it looked.
So back to the drawing board, I mocked up this "wall" in Word and sent it to Micheal.
Now if you know Micheal personally, you might have thought that the asymmetry of the white and yellow lines would have bothered him, but turns out he loved it! He was secretly not so excited about the graduated color pattern with no white separating lines but was being a good husband and letting me run with my idea so this change was a good one.
So...if you were a more planful person and a not quite so impulsive person you might measure the wall...mark out where you want your lines, etc before you start painting. But I'm not so good at that - and I already had one stripe up right? So I dove in and just started eyeballing it. Generally worked out okay and I ended up doing some planning for the final stripes to make sure everything came out okay. And hey, I used a level to make all PERFECTLY straight tape lines even over a lumpy wall. Micheal has commented several times how impressed he is with my lines which is a HUGE compliment coming from him!
I really love it and I look forward to hanging the starburst clock my grandparents dug out of their basement for me right smack dab in the middle of the wall. I'll do some tips and tutorial type stuff lata as I did learn some things about painting strips that I could share.
