I have several posts that need new sisal. I hate to keep paying such high dollars for a new post if only the sisal needs to be replaced. I wonder how difficult it it to replace the sisal. Has anyone here ever tried it? I have seen several web sites where you can buy the replacement sisal....(can't have oils on it....and needs to be a special size to work).....

Thanks.

I think I have at least four posts in need of repair.
