How do I hang a poster on a crooked wall?
You need to get the right perspective on it. It will appear straight if you can catch the hanging right.
Umm, crooked wall? I guess either hang it crooked or fix the orientation of your view, i.e. stop tilting your head
Get adjustable picture hangers for your posters so that you can easily change the angle of the posters to blend in with the crooked wall. To stick the posters in place, use putty to avoid damaging your walls.
Make the poster crooked...
Crooked wall? Can a wall even BE crooked?? x)
Level the picture
