Finish the edges of the flannel pages by making a buttonhole stitch around the edge with a 60" length of Size 5 Pearle cotton for each half of each page. You may also choose to finish the edges of your pages with pinking shears, a small zigzag stitch, sheer seam binding, or bias cut silk ribbon.

In order to be able to work with a manageable length of floss, fold the pages in half on the straight of grain of the fabric, and mark with pins. This straight of grain is the "fold" in the center of the pages, where they will be attached to the inside pieces of the needlebook. Start and stop your buttonhole stitching at these points so that your beginning and ending knots will be covered by the stitching that attaches the needlebook pages to the inside pieces.

Note: To help estimate the amount of floss you would need to finish the edges of any project in such a way that you would not have to knot the floss and start with a new piece at a place where that knotting would be visible, first measure a piece of floss and then make 2" of buttonhole stitches on a scrap fabric. Knot and cut your thread and measure the remaining floss in your needle. Subtract this from the amount you started with, and you now know how much floss it takes to make 2" of buttonhole stitches. Divide this in half for the amount of floss needed for 1" of buttonhole stitches. Measure the distance of the cut edge that you will be finishing, and multiply by the amount of floss used to make 1" of buttonhole stitches. This is the length of thread that you need to complete your buttonhole stitches with one continuous piece of floss.
