I made one eons ago and used a heavyweight cotton without any batt or interfacing. I bound the edges with bias tape. It was great, because it was totally washable. The book was sewn through the middle pages. There was a different colored pick up truck on each page. A buttonhole was on the bed of each and a pocket stitched to the back of the page. I made little cut outs for each page from interfacing. The items were then to be placed in the truck of the same color. If I did it now, Velcro would be my friend!
