Someday if the Lord blesses us with grandchildren and I have more free time to sew, I'd love to make a book like this! This Etsy seller has so many good ideas for pages to put in the book! (Abacus page for Your Very Own Quiet Time Book project)
Button Geoboard page!!! Could have several pictures drawn out in the background, each in a different color, then have a the different colored strings that they wrap around the buttons to make the shapes!
