And I just received more of it, but the 11" looks like the 4" this time, it doesn't have the zig-zags. Does this mean I can cut anywhere, as long as I don't cut through the black parts?
Hopefully my boa will be all set up in his new enclosure tonight; the heat is just one of the finishing touches!
Yup. Just cut along the clear areas between the black parts. Just like the 4inch kind.
