Also, if you find yourself knicking your fingers, don't take a picture of it. Just go and wash your bloody hand.
Do not worry about making the holes the full centimeter wide. In fact, I suggest against it. The holes will naturally get wider as you shag.
I'm just getting dirtier and dirtier with this blog post.
Remember that all strips -- with the exception of the edge pieces -- with share their holes* with two other strips. That means, for the second strip, thread it halfway through the second hole and the other end through the third hole.
Don't be afraid to cut up strips as you go along. And remember that the possibilities are endless: if you want to do a pattern, do a pattern. If you want to a certain color scheme, do a color scheme. I lucked out in that most of my old clothing is pastel-colored, so I got the nice contrast of the white socks and pastel shirts with the black socks and the one rogue dark-colored shirt.
*Heh, share their holes.
