inspired by this i decided to spend some time yesterday "pulling rope" with Polarn... dunno how much he helped tho, he mostly grabbed the end of the rope and pulled it away the wrong way so that i had to get up and go fetch it again... I might add my fingers does hurt today from tying all the knots... But Polarn found it funny to help out tying all the rope and he seems to enjoy his new swing climbing all over, also I might add that if I were to redo it I would probably opt for shorter peices of rope... think the blue rope used was 25 meters, and it is one single continious peice, the white is 3 ropes 10 meters each... anyways heres a little picture (also added a swing under it, wich he seem to like using when I am sitting at the somputer, puts him just below shoulder hight).

as you might see i decided to go with wood instead of pvc, gives him something to chew to peices

also I was slightly worried about all that rope and the risk of him getting tangled, but i managed to tighten it up so they got pretty high tension so I cant move the ropes (in the mesh) anything, and I figured if I'm not possible to move em around or anything Polarn shouldnt be able to seeing he is only 1/200 of my weight hehe.
