Do it yourselfers

This isn't about adult relationships but I couldn't find a better group to put this in. 
My husband fell and his hand went through the wall. It's a good size hole...we are renting an apartment so I'm wondering if I need to give in and call maintenance or patch it ourselves. I've never done a patch before. If you have any tips for doing so o would greatly appreciate them:)      (My hand for scale, he's a pretty big guy)
