How do you make a backyard wrestling and boxing ring?

The best way to make a ring is to get a wide and big trampoline and get three really really long ropes then get 4 tall poles that are slim and place the ropes around them ,tie it and when you do that there is something that hold the trampoline so place the poles above that and make sure you have selected a place for it to stay because other Words you cant take the poles off. Then it should look something similar to a Wrestling ring. 1) U MAKE 12 WELDED HUKS. 2)GET 3 90 OR 70 INCH ROPES. 3)GET 4 9FT POLS.(ASK MOM OR DAD TO TAKE YOU TO WEAR THEY MAKE FENSES) 4)LAST BUT NOT LEAST GET A CERCIL OR A SQUARE TRMPOLINE.
