I cut two strands of wool twice the length I wanted my hair to be, then lined up the end of the wool still attached to the ball with the ends of those strands. Then I folded the strands in half and braided the three strands into my real hair, one strand of hair to each strand of wool, leaving half of the 2 cut strands and the strand attached to the ball free (but attached to my hair at the root). At the end of my hair I stopped braiding and tied the wool strands together leaving three strands of loose wool, THEN I used the strand attached to the ball to wrap the braid and the two loose strands. when i got to the end of the braid I kept wrapping the 5 strands of loose wool... at the end I just tied them together (I was going to seal them to make neat blunt ends but decided the loose wool was cute).
Mine was heavy (too heavy for my poor follicles =( ) but if you put more of your real hair in a section and/or don't add so much length it won't be so bad.
