Angela – I use the clear covers meant for binding from the Office place, and the plastic/leather-look backers. Obviously if you want something hardcover, you are going to need hardcover thickness. The gen. covers make it more like a paperback.
Angelina – With the spines, I only ever used the proclick spines, because thats the reason I got it (rofl) I’m also not very fond of spiral binding, its too flexible, like my Teaching Textbooks book looks like a wave, and is probably warping the pages, also, opening and closing the cardbaord covers on them tend to mean they start to wear and the whole lot of papers fall apart. But I’m picky with spines, so the pro-clicks are the first ones I have liked. A LOT of people seem to use spirals, because the cost is cheaper, I’ll just double check the ratio.
Okay so its supposed to be a 3:1 ratio for the spiral, but someone has used a 4:1 and it worked fine.
