For the most part, we consider fabric books as those for young children. Consider making one for your sewing samples. Or make a Sewing To Go Book (that name just popped into my head) with pockets to hold floss, needles, scissors and other small supplies!
This is my sewing portfolio that I designed and made a couple of years ago. It has a magnetic bag closure and lots of pockets. I could have added take out pages using velcro strips - maybe another time. However, the glue stick is kept in place with velcro. A strip of the soft side of velcro is stitched on the wide fold over section and the sticky piece is stuck on the glue container. It works quite nicely.
I think this book from Shade Tree Art, can also be made with children in mind. For example, each page could be a different colour with applique figures added. I found a couple of tutorials for children's books here and here (this one is made from scraps). Add this one about shapes. You get the idea!
