This is a test I did this morning, it is flawed, now I see what I must do now to get this done.
When finished the Batcave wall will be roughly 10' x 3'
It will be semi permanent and made out brown shipping paper, I came across a roll that someone was throwing out.
Free wall!
Here is a comparison photo
and the new stuff.
Interestingly enough the test strip is turned sideways and still holds up ok.
I'm still going to have to match everything up a little better though.
