I made a chalkboard poster for LO's 1st birthday and when I picked it up this morning it has a giant white border around the whole thing. I don't think cutting it with my paper cutter or knife will yield a clean edge since it is on thick cardboard. I had it done at Costco and they wouldn't cut it for me either and they said they can't avoid the border.

What should I do!? Photoshoot is tomorrow! Should I try to find a frame today or leave it Or...? Any suggestions?

Thank you!!
