Grammatically Incorrect Cross Stitch

So we're traveling and I'm sitting in the hotel at night time working on this counted cross stitch project.

I get this far into the project when it dawns on me that something is not right.  The legal studies major in me kicks into gear and I realize the pattern is grammatically incorrect.  :(

"Who's got the button?" is the equivalent of "Who is got the button?"  Who is going to believe anyone talks like that? :)  The pattern should read "Whose got the button?"  So now I am redrafting the pattern so that it doesn't appear as if an English second language student designed it.  What a pain in the "butt" :(
