For the six player version you'll need six whool tiles, for the four player version you'll need four whool tiles.
First, cut out all the pieces with the laser printer and glue the two hexagons to eachother. Then glue the third piece of wood (the remaining piece which doesn't have whool written on top of it) onto the hexagon with the engravings on it. Glue the last piece of wood (which has written whool on it) on top of this piece. You have now made a hill where your sheep will graze! :)
Oh yeah, the sheep. Just glue them to the tile like you did with the trees for the wood tile. Mine failed a little bit, so I didn't have the opportunity to finish these tiles yet. Hopefully you'll do better!
If you are using board which isn't 4mm thick, you will need to resize the holes for the sheep so that they will fit the board.
Repeat this step for every tile of whool you need.
