I made Mina's and it turned out good. I went to the lumbar store and got plywood that are 3 feet by 3 feet and a huge round pice of wood. I bought 2 4x4 carpet squares at our local carpet store. I found the sisal rope at a local craft store. I just stapled one of the carpet squares to the ply wood and drilled a hole for the screw that I put into the round piece of wood, and then connected them together, and then I screwed the other piece of plywood to the top and stapled the other carpet on that.

Now when I did the post I both stapled and used wood glue to attach the sisal to the post and just carefully wrapped it around the post. I took some left over carpet and a piece of leather strap that I had around the house and made a little carpet mouse that I stapled to the top of the post for Mina to play with. It came out cute, but I could of saved myself 10.00 bucks by going to Wal-Mart and purchasing one just like it for 9.99.
