1) Judging from other threads on here, your bumpers as they are won't pass inspection. I'd suggest making bands of fabric 2.5" wide that velcro around the ends if you can't find a slicker way of doing it.

2) As for the corners, the bumper section of the game manual will hopefully answer any question you have on what to put in that corner. It has diagrams of a number of solutions. Important to remember: The manual is literal, so you don't have to do anything that it doesn't tell you to. I don't believe it has anything to say on whether the corners need to be connected, so you shouldn't need to.

Hope this helps
