I got Colin's name and giraffe up on the wall yesterday! My replacement came in and I went straight to work. Only problem - the same thing was happening as last time! I used a hair dryer like the demonstrator suggested and it did help but still took me nearly an hour to get up on the wall!
I added the giraffe at the end and he went up effortlessly. You would have thought he was created for the sole purpose of being on Colin's wall. There was no way he wasn't going to stick. So it definitely wasn't my paint (which I was afraid of) or the adhesive since they would have been cut from the same material.
And I put the extra giraffe at the bottom of his door on the inside (see it?).
