The most economical way to bind your book is spiral. We typically use clear plastic spirals for our projects but we can order virtually any color you desire. The advantage of spiral, other than cost, is that the books lay flat when you open them and stay open. An additional advantage is that it allows you to readily add additional pages to your book. We can easily bind just a few pages or more than an inch of paper. We charge for every 100 pages that we punch and spiral. We typically include a clear front and a solid back plastic cover. The cover allows you to see through to your first page and gives some support and protection to the back.
