I have some stuff that I really like. Can't remember what it's called but it's marketed by C&T Publishing. It's fusible and almost completely dissolves when wet (I tried a piece in water without fabric). I use the gluestick method when turning under the edges and machine appliqué with monofillament. I think 25 pages was $10. Not cheap but not outrageous either. The appliquéd fabric is very soft after rinsing and doesn't feel as if anything is left under it.
