Hi, I have made many fabric books for alzheimer sufferers.The thing to remember is to make sure any buttons or other fastenings are really securely fastened.I backed all the pages so that the stitches were hidden.Velcro is great to use as it can be ripped open and closed easily,but again must be secure at one end.I also liked to use things like ribbons and lace.One thing that proved popular was suspenders, don't know if you call them that in America, the fasteners to hold up ladies stockings.Things like that help to jog the memory too,not just for the ladies ---for the men too ! Anything tactile, like velvet or soft leather is good also. I've been searching for photographs of the books I've made , no luck so far,We are in the middle of packing to move house after twenty three years,therefore things are in a bit of a muddle. Good luck with your project, you will be blessed by the help and comfort you will give with the blankets. Love Letty
