What did I do? SHIFT-T.....?

So I pressed SHIFT-T (in trying to view the tools, it was just plain T, duh) anyhow, it added something that looks like a lattice to my mesh (but it is not)… How do I get rid of it? It’s too late for undo…

thanks!

Sounds like you are showing the texture Space. You should be able to turn it off in the Object properties
