Extra-strength yarn (I used three colours – 1 skein of the main colour and a bit of the other two) · knitting needles (appropriate for the choice of yarn, I used 6mm) · crochet hook or yarn needle · 7 meters sturdy rope (determine length by measuring height to ceiling) · 2 x stripwood (cut to 25cm long. Make sure they’re wide enough to fit the rope with enough room around) · 2 x D-rings · Optional and depending on method: Sandpaper · drill · ceiling hook.
