My sister makes these and uses the cellophane in one or two pages. She also uses other things like clear vinyl, a Mylar looking substance (for mirrors), buttons, ribbons, small zippers, large snaps, velcro and anything else she can think of to make the more interesting. If it's going to be used for what she calls "church books" (quiet ones) she eases up on the embellishments. She usually uses a thin poly batting but she's also used prewashed terrycloth, flannel and heavy muslin.
