Step 12: Final Thoughts
I did this project two weeks ago, and I noticed a few small edges rolled up from the wall. I promptly card-scraped them back down, and they seem to stay down well. Update: 11/2009 (16 months later): after this first week of scraping down the corners once it settled in to place, I didn't need to do anything to maintain the wall vinyl for the following 16 months it was on the wall. Zero maintenance!
This project turned out really well, and I hope it inspires you to make something neat :)
